Be gentle to all and stern with yourself.
If you can dream it, you can do it.
Who seeks shall find.
I can, therefore I am.
After a storm comes a calm.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
If you're going through hell, keep going.
As my dad said, you have an obligation to leave the world better than how you found it. And he also reminded us to be givers in this life, and not takers.
