If you can dream it, you can do it.
The secret of getting ahead is getting started.
Either you run the day or the day runs you.
The wise does at once what the fool does at last.
Begin to be now what you will be hereafter.
Go for it now. The future is promised to no one.
Always desire to learn something useful.
Problems are not stop signs, they are guidelines.
Know or listen to those who know.
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.
