Inertia, Friction, and Momentum

Early Monday morning, two colleagues sit down at their desks. Amy opens her laptop, but first she has to find the latest files: 10 minutes pass as she digs through disorganized folders (friction). Then an email notification pops up; she stops to read it, then a chat message - context - switch (more friction). By the time she refocuses, a half - hour is gone and she hasn’t truly started her priority task (inertia kept her from rolling). Meanwhile, Ben arrives with a plan: he had set out the files he needed on Friday (reduced friction), he has email snoozed for the first hour, and he jumps straight into the first task. By 9:30, Ben has completed a major chunk (momentum building), whereas Amy is still trying to get into gear. This contrast vignette illustrates something we all face in work: the physics of motion applied to productivity. Inertia means an object at rest tends to stay at rest, and one in motion stays in motion, unless acted on by a force. Replace “object” with “person or task” and it’s eerily accurate: A project sitting idle tends to remain idle (it’s hard to start), but once you get going, you often keep going. Friction are those little resistances - extra steps, context - switches, inefficiencies - that slow you down once you’re moving, or make it harder to start. Momentum is the build - up of motion where continuing becomes easier and sometimes automatic; small wins can lead to more wins as confidence and motivation grow. Understanding these forces in your work helps pinpoint why some days feel like pushing a boulder through mud (lots of friction, no momentum) and others you’re cruising on a roll. The good news: you can intentionally reduce friction and engineer momentum.

List start, stop, and drag factors. Identify sources of friction and inertia in your workflow. Do a quick audit: mentally go through a typical task or day and note where you encounter start - up costs, stop costs, or ongoing drags. Start costs are what it takes to begin a task - e.g., gathering materials, mentally switching from one thing to another, overcoming procrastination. Perhaps for writing a report, your start cost is opening last month’s data, or just the mental hurdle of a blank page. Stop costs are the unwinding or switching costs when you interrupt or finish a task - e.g., if you stop coding mid - feature, the cost later is remembering where you left off (big start - up cost next time). Or stop cost when you leave an email half - written and then re - read to continue. Ongoing friction is inefficiencies during the task - unnecessary clicks, slow load times, waiting on someone else’s input, searching for info repeatedly, multitasking. Write these down for a couple tasks. For example:

Task: Preparing weekly report.

Start cost: compiling data from 3 sources (10 minutes each because format differs = 30 min overhead).

Ongoing friction: copying charts from one tool to another manually, formatting cells (tedious 15 min).

Stop cost: none huge since it’s done when done, but if interrupted, risk of missing a data update.

Task: Coding a feature.

Start cost: setting up dev environment (maybe 5 min), recalling context if picking up old code (could be 20 min reading).

Ongoing friction: doing builds/test taking long (downtime waiting), switching between documentation and code constantly.

Stop cost: leaving code unfinished - risk forgetting logic, possibly introducing bug when resume.

Now target the biggest drags. Perhaps you see the “requests waiting for approvals” as a stop friction in many processes (if your work always has to queue for a manager’s sign - off). Or context switching between email and deep work appears constantly (start/stop friction multiplied). By listing these, you can target the biggest drag points first. If one friction is adding 10 minutes to every instance of a daily task, that’s almost an hour a week - solve that, you win back lots. For inertia, notice what triggers you to procrastinate: do you avoid starting tasks that seem vague? Then clarify outcome (previous chapter techniques) to reduce psychological inertia. Or tasks that require heavy cognitive load might scare you from starting at 4 PM - maybe plan them for morning. In summary, find where friction and inertia are worst, as those are leverage points to fix (remember leverage chapter - removing friction multiplies your throughput).

Remove steps and pre - position materials. Friction often comes in the form of unnecessary steps or poorly timed preparation. Simplify processes by removing or automating any step that doesn’t add proportional value. If you always copy data from System A to B, could you integrate them or at least export/import rather than manual copy? If a form requires 5 signatures just because of old policy, challenge if they’re all needed or can one suffice. Each removed step is like removing a rough patch on a surface - less friction, smoother flow. Pre - positioning is a powerful tactic: set up everything you need before you need it, ideally in a low - pressure time. For example, if tomorrow you need to work on a document, take 5 minutes today to open the doc, outline headings, gather the reference files in one folder. When you start tomorrow, you’re not spending the first 20 minutes “getting ready” - you dive in. If you have a meeting first thing in the morning, prepare the agenda and open all relevant files the evening before or at least first thing, so you’re not scrambling at meeting time. Think of it like staging ingredients before cooking (mise en place). At a team level, pre - positioning might mean ensuring accounts/passwords are set up for new joiners in advance (so day 1 isn’t wasted setting up access), or prepping template emails so that when an event happens you fill 2 blanks and send instead of writing from scratch. Another friction buster: lowering handoffs. Each handoff in a process (passing work to someone else for next step) can introduce waiting or miscommunication. Can you reorganize tasks so fewer handoffs needed? Maybe one person can complete whole chunk versus splitting unnecessarily, or at least ensure handoffs are well - defined and immediate (e.g., use a shared tool that notifies the next person right when you finish rather than waiting for a meeting). Also, prepare resources you’ll frequently use and keep them at hand: if you often need a particular reference, keep that browser tab pinned or manual on your desk. It’s a small thing, but every time you don’t have to search, you save a minute and more importantly avoid losing flow (which can cost many minutes to regain). In sum, to reduce friction: streamline processes (remove unneeded friction points), automate repetitive small tasks (macro, script, or using built features like filters or rules in email), and always be prepping for your next main tasks when you have a lull. Even 5 minutes spent readying an environment (opening all apps, closing irrelevant ones) can sharply reduce friction when you engage in the real task.

Break work into visible, small wins for momentum. Momentum builds when you feel progression. A huge task with a distant payoff often feels like pushing a heavy object from rest - daunting. But if you break it into mini - tasks that each deliver a tangible result (a “shippable” piece or something you can tick off a list), each completion gives you a push of momentum. It’s motivating and also results in concrete progress. For example, instead of “write the entire 30 - page report” as one task, break into “draft section 1 (intro)” then “section 2”, etc., maybe 2 - page sections. Each time you finish a section, it’s a mini victory and psychologically you’re moving. Similarly, in team projects, try to structure so you deliver something - however small - early and regularly. That’s the agile philosophy (each sprint yields some increment). These visible wins create a sense of achievement and forward motion, which fosters motivation to tackle the next piece. Also, make progress visible: use a kanban board or checklist that you update as you complete items. Humans have a bias that seeing tasks physically move to “Done” or percentage bars filling does wonders to our momentum. It’s like watching distance markers when running - knowing you’ve covered ground pushes you on. So track progress publicly (if solo, even on a piece of paper on your desk you cross out done items, or a progress bar drawn). For particularly long efforts, celebrate intermediate milestones explicitly. Perhaps after completing a major deliverable, take a short break or share the interim result with a stakeholder for feedback - their acknowledgment can boost momentum and confidence. Another tip: end your day at a point where you know what the next small win is to achieve tomorrow, so you start the next session already poised for a win rather than staring at amorphous bulk. For instance, some writers stop mid - sentence or at an easy part they know how to continue - so next morning they can finish that quickly (taking advantage of inertia of ongoing task rather than starting new). That quick win then fuels the harder stuff after.

Use checklists and audits to eliminate friction systematically. A weekly “friction audit” can be a 10 - minute reflection: what was one thing that annoyed me or slowed me down this week? Then make a tiny change to remove it. Did you find yourself clicking through 5 menus to do something frequently? Put a shortcut on your desktop or learn a keyboard shortcut to jump there. Did you wait 3 days for an approval that was just a rubber stamp? Maybe next time ping early or ask to pre - approve typical cases. Over time, these small improvements compound. Document the improvement as a checklist item if applicable (“When starting monthly billing, ensure all data from system X is exported beforehand to avoid downtime”) so you remember and maintain the change. Lock in gains: once you find a friction fix, bake it into SOP (standard operating procedure) or habit. E.g., if you realize prepping tomorrow’s to - do list at end of day saved time next morning, incorporate that into your daily shutdown routine (make it a checklist item: “Before leaving: clear desk, list tomorrow’s top 3 tasks”), so it becomes consistent. Checklists can also avoid having to think too hard each time (reducing cognitive friction). Say you always forget one step in a process and have to backtrack - a simple checklist prevents that, making flow smoother with fewer oops moments. The key for momentum is also to limit Work in Progress (WIP). Too many parallel tasks (excess WIP) creates friction via context switching and none getting done, thus no momentum. Limit how many tasks you actively work on at once (perhaps the team or you decide only 2 tasks on your plate at any given time beyond tiny stuff). This ensures you actually finish things (gaining momentum and reducing that mental load). It’s friction to juggle 5 things in head; it’s momentum to complete one and move to next. Write that WIP limit on your board if needed as a reminder: finish what’s started before grabbing a new toy. Another anti - friction measure: reduce multi - tasking environment. If you find lots of friction from external interruptions, create a habit or policy such as “two - hour focus block daily (no meetings, notifications off).” That cuts friction of context switching and start - stop beyond your control. It may feel “oh, but I need to be responsive” - you can train colleagues that 10 - 12 is your focus time and you’ll respond after, which is perfectly workable. Protecting contiguous time is like smoothing out a bumpy road - less friction, better momentum.

Stack new tasks onto established habits for free momentum. Inertia is strongest when starting from complete stillness. But if you piggyback a new behavior onto an existing routine, you leverage momentum from that routine. For instance, if you want to add a daily code review session (and you already have a daily morning coffee routine where you quietly read news), you might do code review while having coffee instead. The existing habit (coffee + reading) carries you into the new task easily - you were going to sit and read anyway, now you read code. This concept, known as “habit stacking,” reduces friction of initiating the new activity because you tied it to a trigger and momentum you already have. Another example: you need to do daily exercise but always skip - if you already walk your dog at 7 am, maybe add a 5 - min jog at the end of that walk. You were out anyway (inertia overcome by dog’s demand), so tack on the new. At work, if after lunch you usually chat or browse internet and find it hard to get back to work, intentionally attach a productive low - resistance task to that routine: e.g., after lunch (trigger), I will spend 10 minutes cleaning my inbox or brainstorming ideas (something mildly engaging to transition). That small action builds a little momentum and soon you’re back in work mode for the afternoon. It’s easier to modify momentum than to create it from scratch. Another momentum trick: plan your work such that tasks naturally lead to each other smoothly. If task B requires you to wait after finishing A, maybe find a way to begin C in that wait to not lose momentum. Or group similar tasks (batching) so you stay in same mode. For example, instead of scattering email checks all day (constant stop/start relative to other work), do all your email replies in one batch mid - morning and one batch late afternoon. You’ll find you are in “email mode” and can plow through them faster (less reorienting friction each time), and your mid - day deep work wasn’t peppered with stops. Batching also reduces the overhead per item, building a rhythm (like assembly line momentum). Just ensure you don’t ignore truly urgent messages - but those are rarer than we act. Stacking and batching are about aligning tasks with a smooth velocity vector, rather than constantly changing direction (which in physics is friction or wasted energy).

Measure and reward momentum’s benefits. If you implement a friction fix or momentum booster, measure its effect to reinforce the value. For instance, track how long you spent on a certain report before and after simplifying steps. If you saved 1 hour, note that (maybe even monetarily if relevant - e.g., at $X hourly rate, that’s $Y saved). Or notice qualitatively: “We removed the daily sync meeting (friction) and replaced with a chat update, and our project still on track plus regained 30 min each day.” Recognizing these improvements with data or anecdotes helps maintain them (people might slip back into old habits unless they clearly see the new way is better). If you lead a team, celebrate when someone identifies and removes a friction point. “Hey, Sarah’s idea to auto - generate part of the report saved us all time - great work.” This encourages the continuous improvement culture. Similarly, acknowledge momentum wins: “We finished 5 feature tickets this week, way to go - those daily goals really kept us on track.” In personal life, maybe reward yourself when you stick to a momentum - building routine all week (like focusing first 2 hours each day on top priority, which yields progress). The reward could be as simple as taking Friday afternoon off because you already got so much done (benefit of momentum). This positive feedback loop will make you more likely to keep seeking friction to remove and momentum to gain. Over time, you might notice you now have an intuition for when friction is creeping in (“this meeting seems like added friction, do we need it?”) and when momentum stalls (“team hasn’t delivered anything visible in a while, morale might drop, let’s create a quick win”). Then you can proactively adjust, making you kind of the motion manager of your work, keeping things gliding forward with minimal drag.

By consciously reducing those tiny (and sometimes not - so - tiny) frictions and actively cultivating momentum through small wins and habit piggybacking, you transform how your work feels. Tasks that used to feel like dragging a sled through sand start to feel like rolling on wheels. You’ll notice you approach work with less dread (there’s a plan to avoid slog) and more zest (once you start, you know you’ll get on a roll). Combining this with the leverage concepts from the last chapter, you’re optimizing both where you apply force and how smoothly that force translates into motion. Now, as we carry on, we’ll tackle one of the most challenging parts of any endeavor: simply getting started. We touched on inertia here; the next chapter dives deeper into beating the initial activation energy hump and establishing starting routines that essentially kick inertia to the curb.
