Whatever it is you're trying to do with your life - improve health, nurture relationships, parent better, lose weight, cook more, improve fitness, run faster - the fact of the matter is, sometimes you're going to suck at it, sometimes you're going to fall.
Getting mad at yourself that something inevitable happened, well that's not very helpful.
Instead of spending time and mental energy on being upset that you fell, instead focus your attention on getting back up.
Easiest question to help you to do so?
"What can I do today that will help?", and then do it.
Falling down doesn't matter. All that matters is that you get back up.
