Either you run the day or the day runs you.
If you can dream it, you can do it.
By failing to prepare, you are preparing to fail.
Go for it now. The future is promised to no one.
Know or listen to those who know.
Do not weep do not wax indignant. Understand.
It's always too early to quit.
Be thine own palace, or the world's thy jail.
Expect problems and eat them for breakfast.
You never know what motivates you.
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.
