It's always too early to quit.
Well done is better than well said.
If you think you can do it, you can.
Leap, and the net will appear.
If you can dream it, you can do it.
Never complain and never explain.
The dog that trots about finds a bone.
Know or listen to those who know.
Problems are not stop signs, they are guidelines.
Either you run the day or the day runs you.
Leave the atom alone.
