It's always too early to quit.
To know oneself, one should assert oneself.
Be thine own palace, or the world's thy jail.
Never complain and never explain.
Who seeks shall find.
I can, therefore I am.
You never know what motivates you.
If you're going through hell, keep going.
Do not weep do not wax indignant. Understand.
Know or listen to those who know.
Strength is a matter of the made-up mind.
