To be a good loser is to learn how to win.
You never know what motivates you.
It's always too early to quit.
Do not weep do not wax indignant. Understand.
Leap, and the net will appear.
Be gentle to all and stern with yourself.
If you think you can do it, you can.
Be thine own palace, or the world's thy jail.
Be kind whenever possible. It is always possible.
Never complain and never explain.
There is as much wisdom in listening as there is in speaking - and that goes for all relationships, not just romantic ones.
