Know or listen to those who know.
Leap, and the net will appear.
If you think you can do it, you can.
If you've got a talent, protect it.
Be gentle to all and stern with yourself.
If you're going through hell, keep going.
Who seeks shall find.
It's always too early to quit.
The wise does at once what the fool does at last.
Expect problems and eat them for breakfast.
The work on ants has profoundly affected the way I think about humans.
