from Moral Letters to Lucilius · tr. Richard Mott Gummere (1917)
Letter II
The primary indication, to my thinking, of a well-ordered mind is a man's ability to remain in one place and linger in his own company. Everywhere means nowhere. When a person spends all his time in foreign travel, he ends by having many acquaintances, but no friends.
This text is one of the sources behind Seneca, one of the voices you can reflect with.
