If you think you can do it, you can.
What you do today can improve all your tomorrows.
Well done is better than well said.
The dog that trots about finds a bone.
Wherever you are - be all there.
After a storm comes a calm.
It's always too early to quit.
Know or listen to those who know.
Leap, and the net will appear.
Things do not happen. Things are made to happen.
Science is a differential equation. Religion is a boundary condition.
