Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
You never know what motivates you.
The wise does at once what the fool does at last.
Leap, and the net will appear.
Do not weep do not wax indignant. Understand.
What you do today can improve all your tomorrows.
If you think you can do it, you can.
Things do not happen. Things are made to happen.
If you've got a talent, protect it.
All science is either physics or stamp collecting.
