You never know what motivates you.
If you can dream it, you can do it.
Know or listen to those who know.
The dog that trots about finds a bone.
The secret of getting ahead is getting started.
If you're going through hell, keep going.
Do not weep do not wax indignant. Understand.
Only the educated are free.
Expect problems and eat them for breakfast.
Well done is better than well said.
Science is a self-sufficient activity.
The thing about science is that it's an accurate picture of the world.
