"If you're not failing, you're not pushing your limits."

"Look at every mistake as an opportunity to learn and improve."

"Mistakes are acceptable if you learn from them; unacceptable if you don't."

"People who worry about looking good typically hide what they don't know, and people who are more concerned with achieving goals expose what they don't know."

"Pain plus reflection equals progress."

"Don't judge a man by where he is, because you don't know how far he has come."
