I'm pretty sure the reason most people never pick a specific thing they want to do something about & actually make a genuine effort is that no matter how much they may tell themselves that's the way things get done, they already know that's not true.
As long as they don't try it out for real, they don't have to be confronted with what that means. It rocks your comfortable world. It confronts you with the fact that you are in a prison, tightly controlled with no say in anything.
