To know oneself, one should assert oneself.
Things do not happen. Things are made to happen.
The wise does at once what the fool does at last.
What you do today can improve all your tomorrows.
The most effective way to do it, is to do it.
You never know what motivates you.
After a storm comes a calm.
Begin to be now what you will be hereafter.
Expect problems and eat them for breakfast.
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.
