Never complain and never explain.
Be thine own palace, or the world's thy jail.
The wise does at once what the fool does at last.
It's always too early to quit.
I can, therefore I am.
Problems are not stop signs, they are guidelines.
Do not weep do not wax indignant. Understand.
To know oneself, one should assert oneself.
If you've got a talent, protect it.
Know or listen to those who know.
The greatness of a man's power is the measure of his surrender.
