I've pretty much stopped when I stopped having the desire to get the Jordans I want. Usually, when I do not get the Jordans I want on release day, I scourthe internet and ebay for good prices.
But now, like when I missed the CDP XI/XII, even though I wanted both real bad and was the only pack I wanted, it didn't motivate me enough to look forthem after I missed them.
I think that was a clear sign, to me at least, that I have moved on. I actually need to move and sell some of my shoes to make some room in my closet for othershoes (non-jordans) I've purchased.
I haven't even worn Jordans in about 2 years now.
