Without hard work, nothing grows but weeds.
If you think you can do it, you can.
Wherever you are - be all there.
To be a good loser is to learn how to win.
Know or listen to those who know.
Be thine own palace, or the world's thy jail.
If you've got a talent, protect it.
The dog that trots about finds a bone.
Never complain and never explain.
After a storm comes a calm.
