Retire into yourself as much as possible. Associate with people who are likely to improve you. Welcome those whom you are capable of improving. The process is a mutual one. People learn as they teach.
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 YoungerAs gratitude is a necessary, and a glorious virtue, so also it is an obvious, a cheap, and an easy one; so obvious that wherever there is life there is a place for it; so cheap, that the covetous man may be gratified without expense, and so easy that the sluggard may be so likewise without labor.
