I taught at a community college for a few years and have spoken at conferences. Those engagements are immensely enjoyable and energizing to me because they're performances. The roles of the audience and presenter are clear. I do my thing and the audience does theirs. I get that energy and enjoyment (a ton more of it, actually) performing live music. I walk off a stage jazzed. It's a wonderful high.

The dinner party scenario is absorbs energy. It's not necessarily less enjoyable than performing, but because it's peer-to-peer there's so much more protocol, nuance, and thought than performing. Even if I'm talking with people I know well I don't walk away energized. With people who are new to me it's a lot of work. Like anything it has come easier w/ practice.
