Quality is not an act, it is a habit.
If you're going through hell, keep going.
If you think you can do it, you can.
If you can dream it, you can do it.
Only the educated are free.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
Always desire to learn something useful.
The nature of God is a circle of which the center is everywhere and the circumference is nowhere.
