"The greatest mistake I ever made in my education was failing a physics course at Cornell. I opted to take an auto-tutorial class that did not require calculus because I was afraid to make math errors. Up until this point, I had never failed at anything. It was a turning point for me. I had to dispel prior notions of learning to succeed. I accepted that there would be many errors along the way. I relearned the basics I had previously memorized through difficult examples and repeated, detailed lab work."
