To know oneself, one should assert oneself.
By failing to prepare, you are preparing to fail.
If you've got a talent, protect it.
Expect problems and eat them for breakfast.
The wise does at once what the fool does at last.
Only the educated are free.
Things do not happen. Things are made to happen.
Never complain and never explain.
It's always too early to quit.
Know or listen to those who know.
People are famous for being famous and for nothing else. And good luck to them, because it lasts about a year and then they're nothing again.
