That applies equally to me as well, and probably to most of the regulars around here
Some guys do breeze through here on their way to creating the perfect Aero, Thedi, Langlitz, at Cetera, and once they get that jacket we never see them again. Those are the guys who may actually have found their grail jacket, or at least a jacket that comes close enough and then they move onto other things.
For the rest of us, it is absolutely an endless quest and once the jacket that we have put so much time and energy into arrives we are already itching to start in on the next one.
I'm definitely one of the former - been here to educate myself on my first good jacket, and don't have any plans for more after that. I'm enjoying the learning/customization process quite a lot, but also want it to end soon so I can have my jacket! I think @El Marro is completely right, and that his categories apply to pretty much every discussion board that exists and is devoted to things and/or hobbies. Doesn't seem to matter what the 'content' is - watches, shoes, tablets, superhero statues, cars - discussion boards always seem to unite those who are lifelong perfectionists/completists/whatever you call it. Discussion board communities probably reinforce and encourage the habit, what with all the positive reinforcement people give and get on them (this board, for example, is amazingly complimentary about other people's jackets). It's one of the (few) positive results of the internet - the ability to find communities of like-minded 'lunatics', regardless of geography .
Still, I think ton is crazy to have sold that jacket !
