Always desire to learn something useful.
Begin to be now what you will be hereafter.
Be gentle to all and stern with yourself.
Be kind whenever possible. It is always possible.
If you're going through hell, keep going.
To be a good loser is to learn how to win.
Well done is better than well said.
Quality is not an act, it is a habit.
I can, therefore I am.
Do not weep do not wax indignant. Understand.
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.
