Both, if possible. To be honest, your post is dripping with pretension. Do you think you're gifted with some special wisdom about adulthood due to having reached the ripe old age of fifteen? Most adult Lego fans have been at the point you're at where they thought they had "grown out" of Lego. Then, eventually, they grew out of the idea that "growing out" of Lego has to be a thing. It's so common that AFOLs have a term for it: the "dark ages", the years between abandoning a favorite hobby due to teenage pretensions of maturity and then rediscovering it as an adult after they learn that adulthood doesn't make the things you used to enjoy any less fun or fulfilling. But again, you're three years out from even being able to consider yourself an adult. I'd love to hear five, ten, fifteen years from now whether your naïve idea of what adulthood entails has turned out the way you plan. Well, I am at the age of sixteen, and, although I am embarrassed to talk about it since no one gets (except for this community) my now rejuvenated enthusiasm for both LEGO and Bionicle, I wouldn't merely just shove it out of my life again after last time that happened around 2012 (Bionicle by 2011) because of my inability to play with it because of my late Chihuahua puppy (he wanted to eat anything and everything and our apartment was small). Unless I can search my garage soon, I might have lost a very large bin of LEGO parts (and some Bionicle parts as well). It would suck, but I'd save and buy someone else's lot at a garage sale or eBay and continue on with my passion that has been sidelined for a while, but not forgotten.
