Who seeks shall find.
Problems are not stop signs, they are guidelines.
Know or listen to those who know.
If you're going through hell, keep going.
Always desire to learn something useful.
You never know what motivates you.
Leap, and the net will appear.
Never complain and never explain.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
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.
