"Mistakes are painful when they happen, but years later a collection of mistakes is what is called experience."

"A dream is your creative vision for your life in the future. You must break out of your current comfort zone and become comfortable with the unfamiliar and the unknown."

"Change the changeable, accept the unchangeable, and remove yourself from the unacceptable."

"Time is an equal opportunity employer. Each human being has exactly the same number of hours and minutes every day. Rich people can't buy more hours. Scientists can't invent new minutes.

"You must learn from your past mistakes, but not lean on your past successes."

"Failure should be our teacher, not our undertaker. Failure is delay, not defeat. It is a temporary detour, not a dead end. Failure is something we can avoid only by saying nothing, doing nothing, and being nothing."

"There are two primary choices in life: to accept conditions as they exist, or accept the responsibility for changing them"
