I do feel like I have already (prematurely) started to limit my social life, etc., to what I already know and like. I’m just 50. Hmmmmm.
Conversely, it kind of makes me feel young to be very picky about where I spend my resources of time and attention.
On an explanatory note, my “young” years were sad, painful, and difficult. When I feel good now, it’s the way I wish I’d felt or handled things back then.
