Motivation for exercise comes easily to me.

Motivation usually shows up about five minutes late — after the shoes are on and you're already at the end of the street, not before.

Waiting for it to arrive first is waiting for a bus at the wrong stop entirely. The feeling gets produced by the movement. It isn't a permit issued in advance to people who feel like it.

Which lowers the bar considerably. You don't have to want it. You have to tie the laces and give the wanting five minutes to catch you up.
