The jokes your friends make about you slowly turn into beliefs you hold about you. Choose your comedians.

Repetition does the work that no single joke manages on its own. A running bit about you being the slow one, the broke one, the one who never gets picked, is funny at first, and somewhere around the hundredth time it stops being a joke and becomes a description you have started agreeing with. Nobody notices the handover while it happens.

Notice which bits get run about you and whether you actually find them funny. You can say one has gotten old without making a speech of it. Friends worth keeping drop it, and the ones who double down have told you something useful.
