What you do today can improve all your tomorrows.
Do not weep do not wax indignant. Understand.
Always desire to learn something useful.
Problems are not stop signs, they are guidelines.
It's always too early to quit.
Never complain and never explain.
Things do not happen. Things are made to happen.
To know oneself, one should assert oneself.
Be thine own palace, or the world's thy jail.
You never know what motivates you.
