That's the way I got along in life. I don't ever r...

I realized that I would have some very tough sledding, and I was very discouraged because I didn't see much hope of getting into the field I wanted to get into with no college education.

It was depressing, very depressing. I worried about how I would make a living. I didn't want to stay on the farm. It didn't offer the challenge I wanted and yet, without a college education, I felt that I was really out of luck.

I think the driving thing was curiosity about the universe. That fascinated me. I didn't think anything about being famous or anything like that, I was just interested in the concepts involved.

I feel like a lot of the female relationships I see on TV or in movies are in some way free of the kind of jealousy and anxiety and posturing that has been such a huge part of my female friendships, which I hope lessens a little bit with age.

Jealousy is no more than feeling alone against smiling enemies.

It's amazing the clarity that comes with psychotic jealousy.

Anger and jealousy can no more bear to lose sight of their objects than love.

Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young.

There is a fountain of youth: it is your mind, your talents, the creativity you bring to your life and the lives of people you love. When you learn to tap this source, you will truly have defeated age.

Life would be infinitely happier if we could only be born at the age of eighty and gradually approach eighteen.

Probably the happiest period in life most frequently is in middle age, when the eager passions of youth are cooled, and the infirmities of age not yet begun as we see that the shadows, which are at morning and evening so large, almost entirely disappear at midday.
