Begin to be now what you will be hereafter.
Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
Who seeks shall find.
Quality is not an act, it is a habit.
If you're going through hell, keep going.
Always desire to learn something useful.
The dog that trots about finds a bone.
Only the educated are free.
Leap, and the net will appear.
Science is a self-sufficient activity.
The thing about science is that it's an accurate picture of the world.
