I've also noticed similar things about most 30-somethings, 40-somethings, and 50-somethings. Most people don't ever really grow up.
I don't entirely know how you were at 22, but I don't think that you fit that description then, either. I'm trying to picture a lazy slugbug with no interest in the world around her..I'm failing. I can't speak to the possible inaccuracies of your self-perception back then, but I can definitely say that to the extent you lacked self-confidence and self-esteem, you were seriously misjudging yourself. As you well know now.
Cheers,
Ben
PS Did I mention, HAPPY BIRTHDAY!
