Now when I feel scared of an opportunity I know I have to take it — it’s a signal that this is something I must do, because the other important thing I’ve figured out is that I am only afraid of the things at which I know I am capable of succeeding. I don’t fear the things I can’t do, because who cares? I’m already certain I’ll never be an Olympic gymnast or a conceptual artist or the kind of person who has an organized underwear drawer all the time and not just for a day or two after they’ve tidied it up. I don’t fear these things at all, I will demonstrate the world’s worst cartwheel for you and not feel even a bit regretful when I look ridiculous. I am only afraid of the stuff I know I can do because I don’t want to fuck it up. I don’t want to be wrong. I don’t want to make a mistake.
This Is Me, Irrationally Feeling Like a Failure

This has been a motivating factor for me in many life decisions, but I’ve never articulated — or even figured out — why. This is why. Thank you for setting it out so clearly.
