If you think you can do it, you can.
Who seeks shall find.
If you're going through hell, keep going.
To be a good loser is to learn how to win.
The most effective way to do it, is to do it.
Never complain and never explain.
Do not weep do not wax indignant. Understand.
Always desire to learn something useful.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
I've done an awful lot of stuff that's a monument to public patience.
