Absolutely NOTHING is a mistake if you learned from it. No matter what you’ve done that YOU think is terrible, no matter what you’ve done that OTHERS think is awful, you have NOT made a mistake if afterward you found a way to grow.
Yep, so you made a “mistake.” Did you sit your butt down, think about it for awhile and realize some things? Did you think of a way you could do it better next time? If yes, then you have not made a mistake, actually what you did was have a mis-take. A miss on the take. You took to doing something and you missed. So what? It’s okay!
Don’t beat yourself up for mis-takes. They are PRECISELY what you need in order to accept yourself, move forward and become successful.
