Most successes are unhappy. That's why they are successes - they have to reassure themselves about themselves by achieving something that the world will notice.
How selfish soever man may be supposed, there are evidently some principles in his nature, which interest him in the fortune of others, and render their happiness necessary to him, though he derives nothing from it, except the pleasure of seeing it.
The gospel of cheerfulness, I had almost said the gospel of amusement, is preached by people who lack experience to people who lack vitality. There is a vague impression that the world would be a good world if it were only happy, that it would be happy if it were amused, and that it would be amused if plenty of artificial recreation - that recreation for which we are now told every community stands responsible - were provided for its entertainment.

It is in everybody's interest to seek those [actions] that lead to happiness and avoid those which lead to suffering. And because our interests are inextricably linked, we are compelled to accept ethics as the indispensable interface between my desire to be happy and yours.
He who finds though that lets us penetrate even a little deeper into the eternal mystery of nature has been granted great grace. He who, in addition, experiences the recognition, sympathy, and help of the best minds of his times, had been given almost more happiness than one man can bear.
You will not rightly call him a happy man who possesses much; he more rightly earns the name of happy who is skilled in wisely using the gifts of the gods, and in suffering hard poverty, and who fears disgrace as worse than death.
Desire is happiness: satisfaction as happiness is merely the ultimate moment of desire. To be wish and wish alone is happiness, and a new wish over and over again.
To be kind, honest and have positive thoughts; to forgive those who harm us and treat everyone as a friend; to help those who are suffering and never to consider ourselves superior to anyone else: even if this advice seems rather simplistic, make the effort of seeing whether by following it you can find greater happiness.
