Be kind whenever possible. It is always possible.
You never know what motivates you.
I can, therefore I am.
Go for it now. The future is promised to no one.
The dog that trots about finds a bone.
Well done is better than well said.
The most effective way to do it, is to do it.
To be a good loser is to learn how to win.
Never complain and never explain.
Without hard work, nothing grows but weeds.
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.
