Ray Bradbury said this quote
“ I know, i know. You're afraid of making mistakes. Don't be. Mistakes can be profited by. Man, when I was younger I shoved my ignorance in people's faces. They beat me with sticks. By the times I was fort my blunt instrument has been honed to a fine cutting point for me. If you hid your ignorance, no one will hit you and you'll never learn. ”
