I think this is great. I feel like most of my possessions are sports equipment, and judging by the contents of my storage room and locker I'm probably right. I have the luxury of having a job I don't need to actually get dressed for (company provided coveralls) so I never shop for either regular clothes or shoes. Every time I do buy something I have a bit of a pang of "do I really need this?" because it seems like I have plenty, though to be honest a lot of the contents of my closet and drawers wouldn't fit me if I tried to put it on. I have a few specific things that I need or want for my upcoming trip to Nepal, but then I should be set for those things for years. I will be starting to shop for a new pair of skis next year, and probably need to think about boots in the next year or two. Again, that pang of guilt. I think "do I really need a storage locker", but the fact is that even the second set of tires pushes me into that situation with my teeny apartment. Then I look around me at so many of the people in the valley I live in that have a massive trailer, boat, ATVs, snowmobiles, etc. and I think that I'm probably not doing too bad.
I think that anything that challenges our prespectives and how we view ourselves and the world is a good thing, though obviously not so much when it's forced upon us by medical issues or something else that's outside of our control. Whether that thing is a challenge to accumulate less stuff, or a challenge to go without TV, or to ski more, I think it's good for us.
Side note, I use GnuCash for tracking finances. I used to use Quicken but when my computer was stolen the program and files were lost so I started with scratch on a free program. It definitely has to be a habit to keep it up, because getting behind on entries and then trying to catch up is a royal pain. It has options to link directly to accounts but I haven't used that.
