Gah! Talking, meeting, schmoozing, networking. These kinds of things leave me drained. I'm no good at small talk--it sounds all right in my head, but once it gets to my mouth, it's all downhill. That's why when I have any doubt at all, I keep my mouth shut to avoid looking like a fool. (Except in the cases where a situation or remark begs to be answered with something pithy and sardonic.) In an extrovert's world, this is of course my fault. Remedy: I need to gab more. But there are seriously some moments when I wish I was climbing Mount Everest instead.
I totally understand, being an introvert myself. I can't stand making small talk with strangers and only feel comfortable if I'm at a party or gathering with people I know. I never know what to talk about with someone I just met. And I hate schmoozing, it's so fake.
