Don't let your mistakes control you because they are proof you tried.
Listen, we've all been there. You try your best, you think you nail a project and boom. A mistake happens. You failed or something went awry. What do you do next? Cry? Scream? Stew on the mistake for hours on end?
Instead of going down that path (which we've all done), I think we should focus more on changing our perspective. Those mistakes we make, well, they are invaluable learning lessons. Things won't always go right because perfectionism doesn't exist. Instead, those mistakes teach us what not to do and how to be better. And, in the end, they show that you were there, you made an effort.
There's nothing wrong with that, right?
