Hello plalo: The Skeezyks has always felt similarly.

No matter how hard I tried, it seemed like whatever I did always ended up being at best mediocre. I have sometimes said... if there is a mistake that it's possible to make, doing something, I'll find it...

However, at this point in my life (I am an older person now...) I've just concluded that one simply has to accept oneself for who one is.
It is true also, however, that highly successful people often fail more than they succeed. It's just that it's the successes we remember. I think it may have been the American baseball player Babe Ruth of whom it has been observed he struck out more times than he hit home runs. Yet he is remembered as one of the great baseball players of all time. It's not how many times you fall down (or get knocked down...) it's how many times you get back up! I wish you well...
