The wise does at once what the fool does at last.
Quality is not an act, it is a habit.
Be gentle to all and stern with yourself.
Only the educated are free.
I can, therefore I am.
The dog that trots about finds a bone.
Do not weep do not wax indignant. Understand.
Always desire to learn something useful.
The secret of getting ahead is getting started.
Wherever you are - be all there.
I am a teacher, and I am proud of it. At Cornell University I have taught primarily undergraduates, and indeed almost every year since 1966 have taught first-year general chemistry.
