"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."

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

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

"Pain plus reflection equals progress."

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

"You can't go back and change the beginning, but you can start where you are and change the ending."
