Self-doubt, lack of confidence, not believing you are good enough, and aiming for perfectionism can block you from attempting anything. It can create a fear of failure. This fear holds you back and you might not even have the courage to try. When you don’t try, you inevitably always fail.
It is a negative feedback loop, because when you fail, it is confirming your self belief that you aren’t good enough and again you will not ontinue to try.
Luckily the opposite is also true. When you believe you are good enough, you don’t strive for perfection but just to be enough. You are hopeful and give it a go. Even if you then fail, you had a chance at success and you would have always learned from it.
As Brene Brown says, when you are not sure if you should or shouldn’t do something, ask yourself:
Is it worth doing, even if I fail?
