If you think you can do it, you can.
Well done is better than well said.
Do not weep do not wax indignant. Understand.
Expect problems and eat them for breakfast.
It's always too early to quit.
Never complain and never explain.
Either you run the day or the day runs you.
Be thine own palace, or the world's thy jail.
What you do today can improve all your tomorrows.
To know oneself, one should assert oneself.
A love of nature is a consolation against failure.
