Be thine own palace, or the world's thy jail.
Never complain and never explain.
Well done is better than well said.
To know oneself, one should assert oneself.
If you've got a talent, protect it.
It's always too early to quit.
To be a good loser is to learn how to win.
Without hard work, nothing grows but weeds.
Things do not happen. Things are made to happen.
If you think you can do it, you can.
