Leap, and the net will appear.
Be thine own palace, or the world's thy jail.
If you think you can do it, you can.
Do not weep do not wax indignant. Understand.
Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
Be kind whenever possible. It is always possible.
To be a good loser is to learn how to win.
Be gentle to all and stern with yourself.
It's always too early to quit.
Most of man's problems upon this planet, in the long history of the race, have been met and solved either partially or as a whole by experiment based on common sense and carried out with courage.
