Quality is not an act, it is a habit.
Do not weep do not wax indignant. Understand.
Without hard work, nothing grows but weeds.
The wise does at once what the fool does at last.
After a storm comes a calm.
The dog that trots about finds a bone.
To know oneself, one should assert oneself.
If you think you can do it, you can.
You never know what motivates you.
Be kind whenever possible. It is always possible.
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.
