Leap, and the net will appear.
Only the educated are free.
Be thine own palace, or the world's thy jail.
After a storm comes a calm.
What you do today can improve all your tomorrows.
You never know what motivates you.
To know oneself, one should assert oneself.
Things do not happen. Things are made to happen.
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.
