True friends are the whole world to one another; and he that is a friend to himself is also a friend to mankind. Even in my studies the greatest delight I take is of imparting it to others; for there is no relish to me in the possessing of anything without a partner.
Seneca the YoungerAs Lucretius says: 'Thus ever from himself doth each man flee.' But what does he gain if he does not escape from himself? He ever follows himself and weighs upon himself as his own most burdensome companion. And so we ought to understand that what we struggle with is the fault, not of the places, but of ourselves
Seneca the Younger
