There have been times when I was beginning to go in that direction, but aside from winding up having 5 wheels and only one bike, I have almost the opposite problem. I give away stuff I decide I don't really need, talk myself out of even basic purchases these days. I'm happy with what I have and aside from **** breaking/wearing out have generally lost the urge to buy more bike stuff. I have one fixed gear bike, it's my only bike, and it's mostly been that way for the last 6 years.
