"I was thirty years old before I learned how to learn things. Nobody has ever taught me. Either I could do things or I couldn't, and there was never anybody who explained to me that no, you have to study. You have to fail. And keep failing better (and trying different things and researching and stuff) until you're not failing any more."
Oh god, this is me too. I was brought up to believe that people are good or bad at things and that's that, nothing you can do about. The impact on my education was terrible because I soon decided that I was just "bad" at anything I found difficult!
