If you've got a talent, protect it.
If you're going through hell, keep going.
Leap, and the net will appear.
After a storm comes a calm.
To know oneself, one should assert oneself.
Who seeks shall find.
Be gentle to all and stern with yourself.
It's always too early to quit.
If you can dream it, you can do it.
If you think you can do it, you can.
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.
