“The worst thing that happens to you may be the best thing for you if you don’t let it get the best of you.”

Never let yesterday use up too much of today.

There are three kinds of men. The one that learns by reading. The few who learn by observation. The rest of them have to pee on the electric fence for themselves.

An onion can make people cry but there’s never been a vegetable that can make people laugh.

The man who never makes a mistake must get tired of doing nothing.

The road to success is dotted with many tempting parking spaces.

A man only learns in two ways, one by reading, and the other by association with smarter people.

There are two theories to arguing with a woman. Neither works.

There is nothing so stupid as the educated man if you get him off the thing he was educated in.

Many have learned that the magnitude of lives is not as to their external displacements, but as to their subjective experiences. The impressionable peasant leads a larger, fuller, more dramatic life than the pachydermatous king.

I am not a person who can really sit around and think about regrets because with every bad experience that you have, there is weirdly something good that comes from it.

No one has been a greater botanist or zoologist. No one has written more books, more correctly, more methodically, from personal experience. No one has more completely changed a whole science and started a new epoch.

Science, for me, gives a partial explanation for life. In so far as it goes, it is based on fact, experience and experiment.

I play with microbes. There are, of course, many rules to this play…but when you have acquired knowledge and experience it is very pleasant to break the rules and to be able to find something nobody has thought of.

Traveling around in a little tin box isolates one from the people and the atmosphere of the place in a way that I have never experienced before.
