You cannot be unhappy, or even depressed, while you are not thinking.

We automatically allow what someone will say about us to make us unhappy when we allow what they have said about us to make us happy.

An untamed mind is usually engaged in the pursuit of unhappiness (or even more unhappiness).

The pursuit of happiness is one of the most common symptoms of intellectual immaturity.

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

Like happiness, unhappiness usually springs from a comparison.

Envy is a less severe form of anger.

You cannot, at the very same time, be grateful and unhappy, or ungrateful and happy.

Genuine happiness is not nearly as common as a fake smile.
