It's always too early to quit.
Do not weep do not wax indignant. Understand.
Know or listen to those who know.
If you're going through hell, keep going.
Expect problems and eat them for breakfast.
You never know what motivates you.
Only the educated are free.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
Leap, and the net will appear.
This ceremony and the intellectual aura associated with the Nobel Prizes have grown from the wisdom of a practical chemist who wrote a remarkable will.
