I actually started this a few months ago! It was difficult walking into my LQS the first couple of times after that decision, but I made it! I must admit that I 'fell off the wagon' twice, but I climbed right back on!
The reason that I made this decision -> I hit my limit of 'stash'. When I realized that I could not possibly use up what I had in this lifetime, I let go of the daydreams of more, more, and still more.
