Never complain and never explain.
Be thine own palace, or the world's thy jail.
Who seeks shall find.
Do not weep do not wax indignant. Understand.
Always desire to learn something useful.
Go for it now. The future is promised to no one.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
If you're going through hell, keep going.
If you've got a talent, protect it.
A sense of duty is useful in work but offensive in personal relations. People wish to be liked, not to be endured with patient resignation.
