Being bored is the price we pay for not being insane.

Most sane human beings’ chances of being alive in a thousand years’ time are a hundred times higher than their chances of being sincerely happy for at least ten consecutive days.

Almost everything that will be said or done by someone who is suspected of being insane will seem to confirm that suspicion.

If we had to earn our age by thinking for ourselves at least once a year, only a handful of people would reach adulthood.

Every single person is a fool, insane, a failure, or a bad person to at least ten people.

We would not be ashamed of doing some of the things we do in private, if the number of sane human beings who do them in public were large enough.

Unhappiness is a mild mental illness.

To evade insanity and depression, we unconsciously limit the number of people toward whom we are sincerely sympathetic.

We sometimes use a friend to prevent or stop ourselves from feeling abnormal (or crazy) for liking or enjoying something (or some of the things) that we like or enjoy.
