Happiness and freedom begin with a clear understanding of one principle: Some things are within our control , and some things are not
If you aim to live by such principles, remember that it won’t be easy : you must give up some things entirely, and postpone others for now. You may well have to forgo wealth and power if you want to assure the attainment of happiness and freedom
Stoicism urges us all to be good men and women even-especially-when it is tough to do so. Epictetus teaches that the happy life is the virtuous one.
When individuals feel they are surrounded by nothing but corruption, injustice, and irresponsibility and feel that they are victims of the same and can do little about any of it, Stoicism shows a way to salvation, a way to preserve your integrity and peace of mind even when you are working for a corporation run by modern day Nero's (are there any other kind?), or suffering physically and mentally from the stress of modern life and its overwhelming evils.
Epictetus felt that men and women had a duty to something greater than their own personal ideas of what they thought that their duties and commitments might be at any particular moment. Individuals are citizens of a wider community and what they do should lend harmony to the larger community. Their behavior is not determined by trends but by the highest standards.
