Knowing what is right does not make a sagacious man.
We can do noble acts without ruling the earth and sea.
Happiness depends on ourselves.
You are what you repeatedly do
Men cling to life even at the cost of enduring great misfortune.
But the whole vital process of the earth takes place so gradually and in periods of time which are so immense compared with the length of our life, that these changes are not observed, and before their course can be recorded from beginning to end whole nations perish and are destroyed.
