One thing I must remember: if the options before me are to go for a walk or not, very rarely is not going the better option. Sure, there are times where I can’t go for a walk: I’m busy, or not feeling too well. Those can’t be be helped. But that’s not the same as not feeling like going for a walk.
So when faced with this choice, the default should be to go.
I may feel no improvement.
I definitely won’t feel worse. I’ll usually feel better.
I rarely feel regret.
