Barbara McClintock quotes:

If you know you are on the right track, if you have this inner knowledge, then nobody can turn you off... no matter what they say.

I never thought of stopping, and I just hated sleeping. I can't imagine having a better life.

I know my corn plants intimately, and I find it a great pleasure to know them.

It might seem unfair to reward a person for having so much pleasure over the years, asking the maize plant to solve specific problems and then watching its responses.
