The man who does something under orders is not unhappy; he is unhappy who does something against his will.

There's one blessing only, the source and cornerstone of beatitude: confidence in self.

Everyone rushes his life on, and suffers from a yearning for the future and a boredom with the present. But that man who devotes every hour to his own needs, who plans every day as if it were his last, neither longs for nor fears tomorrow.

There is nothing wrong with changing a plan when the situation has changed.

After death there is nothing.

Whoever has nothing to hope, let him despair of nothing.

If thou art a man, admire those who attempt great things, even though they fail.
