You must take personal responsibility. You cannot ...

Whatever good things we build end up building us.

If you don't like how things are, change it! You're not a tree.

Character isn't something you were born with and can't change, like your fingerprints. It's something you weren't born with and must take responsibility for forming.

The great secret that all old people share is that you really haven't changed in seventy or eighty years. Your body changes, but you don't change at all. And that, of course, causes great confusion.

One of the many things nobody ever tells you about middle age is that it's such a nice change from being young.

My notion of a wife at 40 is that a man should be able to change her, like a bank note, for two 20s.

If you're old, don't try to change yourself, change your environment.

Why should society feel responsible only for the education of children, and not for the education of all adults of every age?

The enemy of society is middle class and the enemy of life is middle age.

We have entered an age in which education is not just a luxury permitting some men an advantage over others. It has become a necessity without which a person is defenseless in this complex, industrialized society. We have truly entered the century of the educated man.

Age is an issue of mind over matter. If you don't mind, it doesn't matter.

Common sense is the collection of prejudices acquired by age eighteen.

The older I grow the more I distrust the familiar doctrine that age brings wisdom.

Wisdom doesn't necessarily come with age. Sometimes age just shows up all by itself.

The best way to find yourself is to lose yourself in the service of others.

The past cannot be changed. The future is yet in your power.
