"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."

"Pain plus reflection equals progress."

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

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

"Mere change is not growth. Growth is the synthesis of change and continuity, and where there is no continuity there is no growth."
