Quality is not an act, it is a habit.
Know or listen to those who know.
Things do not happen. Things are made to happen.
Always desire to learn something useful.
By failing to prepare, you are preparing to fail.
Expect problems and eat them for breakfast.
Be gentle to all and stern with yourself.
Well done is better than well said.
I can, therefore I am.
If you're going through hell, keep going.
I have long considered it one of God's greatest mercies that the future is hidden from us. If it were not, life would surely be unbearable.
