Making mistakes in life is okay, they say. You learn how to make it right the next time, they say. You eventually become better and better through learning from your mistakes. And that seems to be pretty true. But I figured out there's more to it. The practical part of conquering the "how-to" is definitely there, but I realized there's more value to the "try-and-fail" process.
The moment you make a mistake your ego is challenged. You may feel weak, incapable, worse than the others.
You may feel small.
The moment you make a mistake there's your opportunity to understand that we all need help sometimes; we all need each other. Depending on the mistake, you might end up needing someone's knowledge, support, nursing, encouragement, wisdom, or many other things.
Like your 80-years old grandparent or your 5-years old child, you can't do everything by yourself and, at the same time, you can't know whose help you're going to need the next moment...
You see, a mistake has the power to make you feel humble while a success hides the risk of feeding your arrogance. Success is just the hallmark of you having passed through a series of mistakes and failures. Success is just the receipt of your hard work, and the approved ticket to move on to your next series of mistakes.
I don't say start seeking being mistaken over and over again. All I'm saying is, embrace your non-perfect nature. Nobody is born knowing. Observe, apply, evaluate, retry; that's the process, repeated as many times as needed, until we finally know.
