Be gentle to all and stern with yourself.
If you're going through hell, keep going.
Never complain and never explain.
What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
Leap, and the net will appear.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
Quality is not an act, it is a habit.
The dog that trots about finds a bone.
There is no forgiveness in nature.
There is always a certain peace in being what one is, in being that completely.
