Wisdom allows nothing to be good that will not be so forever; no man to be happy but he that needs no other happiness than what he has within himself; no man to be great or powerful that is not master of himself.
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
