If a man is unhappy, remember that his unhappiness is his own fault, for God made all men to be happy.

It is unreasonable to think we can earn rewards without being willing to pay their true price. It is always our choice whether or not we wish to pay the price for life's rewards.

No living being is held by anything so strongly as by its own needs. Whatever therefore appears a hindrance to these, be it brother, or father, or child, or mistress, or friend, is hated, abhorred, execrated.

If you want to improve, be content to be thought foolish and stupid with regard to external things. Don't wish to be thought to know anything; and even if you appear to be somebody important to others, distrust yourself. For, it is difficult to both keep your faculty of choice in a state conformable to nature, and at the same time acquire external things. But while you are careful about the one, you must of necessity neglect the other

If anyone is unhappy, remember that his unhappiness is his own fault... Nothing else is the cause of anxiety or loss of tranquility except our own opinion.

Not things, but opinions about things, trouble men.

Silence is safer than speech.
