We made it, fam. Records have been shattered, legends created, achievements achieved.

For those of you who made it to being an adult, what surprises you that you enjoy it now? Anything you didn't think you would enjoy as a kid? For the younger posters who feel like they aren't "old people" yet, what terrifies you about getting old?

edit: I can start it off. I'm 30, and I feel like I can kinda speak for both atm. I love cleaning now that I'm older, it's insanely satisfying. I almost love it so much that I sometimes let things get a tiny bit messy just to see the drastic progress 20 mins of work can take to make it look 1000% nicer.

As a "younger" person, I still fear getting set in my own ways. Having the same viewpoint forever and not seeing both sides of the issue and never learning past a certain point. I still feel like as I get older, that's more likely to happen. I see people get good at things, get experience, and their observed answer in their head might not always be the solution, just a product of circumstances and then they think what they experienced is right and nothing else can be the answer. Just freaks me out.
