To know oneself, one should assert oneself.
Quality is not an act, it is a habit.
Expect problems and eat them for breakfast.
Know or listen to those who know.
To be a good loser is to learn how to win.
I can, therefore I am.
The dog that trots about finds a bone.
Do not weep do not wax indignant. Understand.
Either you run the day or the day runs you.
Always desire to learn something useful.
God sleeps in the minerals, awakens in plants, walks in animals, and thinks in man.
Science already contained all that was necessary, if you just brought it out.
