It's always too early to quit.
Be thine own palace, or the world's thy jail.
Well done is better than well said.
What you do today can improve all your tomorrows.
Be kind whenever possible. It is always possible.
If you're going through hell, keep going.
Know or listen to those who know.
Quality is not an act, it is a habit.
Leap, and the net will appear.
Expect problems and eat them for breakfast.
The most excellent and divine counsel, the best and most profitable advertisement of all others, but the least practiced, is to study and learn how to know ourselves. This is the foundation of wisdom and the highway to whatever is good.
