Not if you suprise yourself with a party at your place and invite the loudest and most obnoxious people around.
Or if you are really afraid of heights and you suprise yourself with bungee jumping.
Can't you choose to be more interesting? I've been to 3 parties in the past 10 days, a number which I normally don't even reach in a year. It was interesting, to say the least, but really not my niche. The day after I really didn't want to talk to anyone, and if someone did talk, I just wanted to light them on fire. But the parties were interesting.
I suppose you go and do something outside your comfort zone, and see if you can suprise yourself.
