You never know what motivates you.
After a storm comes a calm.
Expect problems and eat them for breakfast.
Who seeks shall find.
Always desire to learn something useful.
What you do today can improve all your tomorrows.
The dog that trots about finds a bone.
Do not weep do not wax indignant. Understand.
Leap, and the net will appear.
Know or listen to those who know.
Science is a self-sufficient activity.
The thing about science is that it's an accurate picture of the world.
