Be thine own palace, or the world's thy jail.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
Go for it now. The future is promised to no one.
Be kind whenever possible. It is always possible.
The wise does at once what the fool does at last.
The secret of getting ahead is getting started.
Never complain and never explain.
Without hard work, nothing grows but weeds.
By failing to prepare, you are preparing to fail.
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.
