In music, push yourself but not too hard; if you play too many sharps you may cut your fingers.

How will I know who I can become if I don't give myself the chance to try new things, to push myself beyond my normal boundaries? Who might I be if I am away from the things that I currently use to define myself?

Don’t say you don’t have enough time or enough money to change the world. You have exactly the same number of hours per day that were given to Helen Keller, Gandhi, Michelangelo, Mother Teresa, Leonardo da Vinci and Jesus Christ.

When you push yourself beyond limits, you discover inner reserves, which you never thought existed earlier.
