You're afraid of making mistakes. Don't be. Mistakes can be profited by. Man, when I was young I shoved my ignorance in people's faces. They beat me with sticks. By the time I was forty my blunt instrument had been honed to a fine cutting point for me. If you hide your ignorance, no one will hit you and you'll never learn.
Ray Bradbury, Fahrenheit 451 (1953)
