Count that day lost whose descending sun finds you with no good deeds done.

Burn the boats as you enter the island and you will take the island.

O Divine Providence, I ask not for more riches but more wisdom with which to make wiser use of the riches you gave me at birth, consisting in the power to control and direct my own mind to whatever ends I might desire.

You know, it's not more knowledge, it's not more education, it's not more facts that we need. It's a better use of what we already have that we need to have. You have each and every one of you, within your potential power right now to do a wonderful job in your chosen field - if you would only embrace it and use it.

If you fail to control your own mind, you may be sure you will control nothing else.

Strength and growth come only through continuous effort and struggle.
