I have a double-edged razor collection, a straight razor collection, a hat collection, a watch collection, a knife collection, a pipe collection, a jewellery collection and the beginnings of a Zippo collection. If you have the collector's mindset, the only way to stop it in my experience, is to stop visiting the relevant forum!
About a year after leaving a watch forum I went back to see what was being discussed. It was, sadly, almost exactly the same ten topics which had seemed very important to me at the time I was constantly mulling over my next horological purchase. While I still love watches and still own more than 15 and still enjoy the ones I have, I now have a bit of perspective and it matters a lot less to me than it did a couple of years ago.
