Problems are not stop signs, they are guidelines.
Who seeks shall find.
Never complain and never explain.
Be thine own palace, or the world's thy jail.
Either you run the day or the day runs you.
Know or listen to those who know.
Be kind whenever possible. It is always possible.
It's always too early to quit.
To know oneself, one should assert oneself.
Expect problems and eat them for breakfast.
