There is cumulative value to investing small amounts of time in certain activities over a long period.

Exercise is an obvious illustration of this principle. There's a clear cumulative effect from exercising a few minutes every day or every other day over a long period of time. At the end of a year, you can see and feel a difference. But at the end of your first exercise session, the only difference is that you are sore. You will see almost no measurable benefit from one exercise session; in fact, no matter how long you have been exercising, there is almost no measurable benefit from a single session. That's why it's so easy to talk ourselves out of exercise. What will it hurt if I miss one day? The answer is, it won't hurt anything, physically speaking. The real value in exercise is not found in any one deposit at a time; the value is realised at the end of a sequence of deposits. Exercise has a compounding effect. It is the consistent, incremental investments of time that make a difference.
