To know oneself, one should assert oneself.
The dog that trots about finds a bone.
Never complain and never explain.
Know or listen to those who know.
The wise does at once what the fool does at last.
Go for it now. The future is promised to no one.
Well done is better than well said.
If you can dream it, you can do it.
If you've got a talent, protect it.
To be a good loser is to learn how to win.
