If you can dream it, you can do it.
Things do not happen. Things are made to happen.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
Know or listen to those who know.
If you're going through hell, keep going.
By failing to prepare, you are preparing to fail.
I can, therefore I am.
