To know oneself, one should assert oneself.
By failing to prepare, you are preparing to fail.
Either you run the day or the day runs you.
Who seeks shall find.
Expect problems and eat them for breakfast.
If you've got a talent, protect it.
Things do not happen. Things are made to happen.
Know or listen to those who know.
Be thine own palace, or the world's thy jail.
Never complain and never explain.
I spent many a summer early morning with the radio very low, half sleeping and half listening.
