It ends if you allow it to. It took me too long, but I have gotten much better at just saying no. Now I am working on lowering the temptation by not looking so much. At this point, in my 2 wheeled world, not much is going to improve my biking pleasure. If anything, lowering my inventory would probably do that better than increasing it. I have been doing that with the thought I would use the dollars from sales to "upgrade" the few bikes I want to keep. I have not done that as I have come to realize that "upgrade" is more about my ego than any performance or comfort gain.
