Becoming a cynic means taking on the responsibility of showing the world what a truly virtuous life looks like, and then trying to teach others how to also live virtuously. Usually by making fun of them.

It's cheap.

Just get a barrel and go live in it.

If you're not sure if a possession of yours is an unnecessary luxury the answer is yes, unless you literally can't survive without it.

If you've got any doubts about what to do, look for a street dog, and just do as it does.
