Rejection-seeking as a form of hiding
When you get rejected, you're off the hook. No promises need to be kept, no vulnerability felt down the road. When you are rejected, you don't have to show up, to listen or to care.
All you have to do is make promises far bigger than people are prepared to believe about you. Or try to be accepted by people who are in no mood (or have no experience) trusting people like you or promises like this.
Seeking out ways to get rejected is a sport unto itself. It's tempting, but it's not clear that it's a productive thing to become skilled at.
Far more frightening (and more powerful) to earn a reputation instead of merely asserting one.
