Being myself

I have realized how I can be confident in being myself recently. Many people say you should always strive to be yourself, which I always disliked, because regardless of how much I wanted to I could see that I am very flawed. How could I ever want to be myself until I was better? How could I even love or like myself seeing all of my flaws? But then I thought about things like how this is my first time ever having to be alive, and I don't even know what life is supposed to be about. I have no frame of reference for what is definitively good other than those around me, who also surely cannot know what good is. Maybe that is the reason to try and be confident in yourself, or instead that is why I am able to allows under any pressure or opposition, forsaking my deepest beliefs when it comes to life in general just because there is a contradicting ideology in existence. So, being as normally unconfident in myself as I am, I depend on this thought because it means there can be no true failing on my part as long as I am trying my best. Therefore, I can be confident within any moment. No thought no matter small and almost insignificant it may be can completely derail my attitude or mindset, before I would spend the entire day being miserable because I may have possibly perceived somebody having a negative reaction towards me, anytime I made an actual mistake in any manner I would be swarmed with despair. I make mistakes all the time, at least a few daily, I am clumsy and I often am dumb when it really matters so you could imagine how often I was upset. The only way I am able to overcome this issue and actually live is by believe in this new idea, because otherwise I would never be able to like myself knowing I am not good enough. It sounds kind of morbid to me when I think about it like that, but it's probably the truth, either I can adopt this idea and be more confident or I can spend the rest of my life hating myself every day, focused on all the ways I am wrong. Tbh I would rather try to be confident and like myself, it's not like I can change who I truly am on the inside, and I hate who I am more than any mistake I make or aspect I could change, so the only choice to escape being miserable is to try this method of being confident.
