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.

We are sometimes dragged into a pit of unhappiness by someone else’s opinion that we do not look happy.

Like alcohol and poverty, a heartbreak has the power to make a man do something he wouldn’t normally do and to make a woman do someone she wouldn’t normally do.

Judgments are the only possible cause of unhappiness and happiness.

We do not become happy. We stop being unhappy.

Even suicidal people can smile.

Some people’s unhappiness caused or was caused by some people’s happiness.

Most people have given back to life the power to make themselves happy.

We are sometimes depressed by our failure to convince people who strongly believe that we are that we are definitely not depressed.
