Most seem to think you should exercise to avoid dying early. That’s an acceptable reason, I suppose, but it misses what I believe to be much more important.
Exercise enables you to function the way you should function. It’s a magnifier of value. It helps you finish writing that book, to travel the world, and to generally become a better person. The key, of course, is that it makes it so that you want to do those things.
We should change the push for exercise from a narrative of avoiding death to one of avoiding mediocrity.
