I can, therefore I am.
Expect problems and eat them for breakfast.
The most effective way to do it, is to do it.
Do not weep do not wax indignant. Understand.
Well done is better than well said.
The dog that trots about finds a bone.
Always desire to learn something useful.
Be kind whenever possible. It is always possible.
What you do today can improve all your tomorrows.
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.
