Be gentle to all and stern with yourself.
The wise does at once what the fool does at last.
Always desire to learn something useful.
If you think you can do it, you can.
To be a good loser is to learn how to win.
It's always too early to quit.
Problems are not stop signs, they are guidelines.
I can, therefore I am.
The dog that trots about finds a bone.
By failing to prepare, you are preparing to fail.
Maybe that's the whole teen oeuvre, you know covering people in disgusting bodily fluids and whatnot.
