If you're going through hell, keep going.
What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
If you think you can do it, you can.
Expect problems and eat them for breakfast.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
Never complain and never explain.
Nobody expects to trust his body overmuch after the age of fifty.
I never expect to see a perfect work from an imperfect man.
