If you're going through hell, keep going.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
Always desire to learn something useful.
What you do today can improve all your tomorrows.
Well done is better than well said.
Go for it now. The future is promised to no one.
The secret of getting ahead is getting started.
Leap, and the net will appear.
The dog that trots about finds a bone.
The biological factors underlying race differences in sports have consequences for educational achievement, crime and sexual behavior.
