Be the same person in public as in private. - Epictetus

So, if you have not been invited to a party, it is because you haven’t paid the price of the invitation. It costs social engagement, conversation, encouragement, and praise. If you are not willing to pay this price, do not be upset when you don’t receive an invitation.

For what else is tragedy than the perturbations ([Greek: pathae]) of men who value externals exhibited in this kind of poetry?

Imagine for yourself a character, a model personality, whose example you determine to follow, in private as well as in public.
