If you think you can do it, you can.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
If you're going through hell, keep going.
The wise does at once what the fool does at last.
Never complain and never explain.
Always desire to learn something useful.
Only the educated are free.
Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
