Either you run the day or the day runs you.
You never know what motivates you.
The most effective way to do it, is to do it.
If you're going through hell, keep going.
The dog that trots about finds a bone.
Do not weep do not wax indignant. Understand.
Leap, and the net will appear.
The secret of getting ahead is getting started.
Always desire to learn something useful.
If you think you can do it, you can.
All science is either physics or stamp collecting.
