Must be a group member before inviting friends
‘Do what thou hast to do, and know thyself’ – that great precept is often cited by Plato;2 each clause of it embraces our entire duty, generally, and similarly embraces its fellow. Whoever would do what he has to do would see that the first thing he must learn is to know what he is and what is properly his. And whoever does know himself never considers external things to be his; above all other things he loves and cultivates himself: he rejects excessive concerns as well as useless thoughts and resolutions.
