It's always too early to quit.
Be gentle to all and stern with yourself.
The wise does at once what the fool does at last.
If you think you can do it, you can.
Never complain and never explain.
Be kind whenever possible. It is always possible.
The dog that trots about finds a bone.
The secret of getting ahead is getting started.
Problems are not stop signs, they are guidelines.
To be a good loser is to learn how to win.
The research rat of the future allows experimentation without manipulation of the real world. This is the cutting edge of modeling technology.
