Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
If you think you can do it, you can.
If you can dream it, you can do it.
Quality is not an act, it is a habit.
The secret of getting ahead is getting started.
Wherever you are - be all there.
Leap, and the net will appear.
Know or listen to those who know.
It's always too early to quit.
The doubt of an earnest, thoughtful, patient and laborious mind is worthy of respect. In such doubt may be found indeed more faith than in half the creeds.
