Why do people around me tend to increase their responsibility load (i.e. have children, become a manager, do charity, etc.) while I (30M) try to avoid it as much as I can?
I had a buddy, and we talked in great detail about this. I chase challenges, and am always looking for the next big puzzle to muddle my way through. He chased freedom. He just wanted to be who he was and spend his time how he wanted.
My point is people are motivated by different things. Find your thing and pursue it. Don't worry what anyone else is doing. You don't answer to them, and they're not any happier than you.
The caveat is don't conflate freedom/motivation with being a dick. Live the life that you want to live, but if that involves disparaging certain demographics for ethically and/or morally wrong reasons, then maybe live a better life than the one you really want to live. This doesn't apply to most people, but there are some out there that should read it and take it to heart.
