That being said, not taking chances, not assuming risks, not trying to succeed for fear of failure, ends up being the biggest disappointment, the heartbreaking regret of “could have.”
Just do it.
Don’t think yourself out of an idea. Go for it. If you fail, it’s going to hurt, indeed, but after a while you’ll realize that you actually learned something out of it. But not trying at all, that’s going to break your heart every single time you remember your failure to act.
