What running injuries taught me about friction, decision fatigue, and building lasting habits
Most habits begin with motivation.
You feel energized, make a plan, and the goal feels clear.
Maybe it's exercising more regularly, improving nutrition, or finally getting enough sleep.
But motivation rarely lasts. Work gets busy, energy dips, and other priorities take over. The plan that felt simple at the beginning becomes harder to follow.
When that happens, we often assume the problem is discipline.
In reality, something else is usually going on: motivation was never meant to carry the whole process.
I ran into this myself when I started running in midlife.
When I first started running, injuries would often derail my routine and send me into weeks of physical therapy.
Over time I learned that stretching before and after runs could help prevent many of these injuries. But even knowing that, I struggled to do it consistently.
The problem was that after a run, I didn’t always have 15 minutes to stretch. I had to get on with the rest of my day, and in that moment it was easy to postpone.
I wanted to avoid injuries and keep running. The issue was that the routine simply didn’t fit easily into that moment.
Looking back, the change wasn’t about finding more motivation. It was about reducing friction and decision fatigue.
A few adjustments made the difference:
Start smaller than you think. A smaller version of a habit is easier to repeat and fits more easily into a normal day. From there, it’s easier to build over time. For me, that meant breaking my stretching routine into short 5–6 minute segments that fit naturally into my day—one right before and after my run and another before bedtime.
Reduce decisions. Deciding ahead of time what you’ll do removes the need to figure it out in the moment. For me, that meant choosing a small set of stretches ahead of time so I didn’t have to think about it after each run.
Expect imperfect days. Missing a day doesn’t mean the habit has failed. Having a simple restart rule can help you return to it quickly. For me, that meant keeping a rule of never going more than two days without stretching.
Motivation can help you begin.But habits last when the routine fits into real life.
