I'm curious as to what you did all this research on and ordered and now you're disappointed. I'm actually the opposite, I'll see something I like/want/must have now and I run to the store and get it. It's a problem that I've been working on for awhile. Once I get my mind set on something I'll do everything in my power to make it work. And it's not just with material things, it's with relationships, and a bunch of other things. When it works great, I'm happy, but when it doesn't I just get more hurt I guess. It sucks to put all that time and energy in something that later on you realize was a waste.
I've got over $1,000 of some stuff I got into a few years ago sitting in my room. I haven't touched the stuff, but at the time I had to have it, and before I was even finished with what I had I was out buying more. Now I'm being lazy and haven't put it on eBay yet. I'll get around to taht eventually. I digress.
