You never know what motivates you.
Do not weep do not wax indignant. Understand.
Only the educated are free.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
I can, therefore I am.
The secret of getting ahead is getting started.
If you're going through hell, keep going.
Expect problems and eat them for breakfast.
The dog that trots about finds a bone.
Science is a differential equation. Religion is a boundary condition.
