I'm lucky enough to not have rituals, but boy can I obsess on some shit! If I take up a new hobby or get a new vehicle, I've got to have everything that goes with it. I can't pass up a deal and have boxes of bike and car stuff in my garage theat I may never get around to installing. And I hear you on taking forever to decide on which of what to get... I can spend hours researching a simple difference.
I'm going to get a new (to me) Cadillac CTS-V when I get home. I search 9 sites daily, looking for a deal.
a few years back I tried several drug options to try and work on my AADD issues, but none seemed to do the trick. My wife is a saint for putting up with me! lol
