Never complain and never explain.

Do not weep do not wax indignant. Understand.

It's always too early to quit.

To know oneself, one should assert oneself.

Be thine own palace, or the world's thy jail.

Always desire to learn something useful.

The dog that trots about finds a bone.

If you've got a talent, protect it.

Things do not happen. Things are made to happen.
