Most of us make a living making someone else's life better one way or another, but for many, it's not the someone else that is the source of passion, but an act instead.

The thing about control is about letting go of perfectionism. If you have an inclination to improve things, you can be overwhelmed by the number of things which could be improved, and it can be demoralizing to see the breadth of it all, and recognizing how little overall impact you, as one person, can have. So you limit your scope. You can't do it all.
