No it makes perfect sense that if you stare at things that you admire you'll start to desire them for yourself. If you never saw them it wouldn't have occurred to you most likely. TPF has that influence and I guess if you want to curb purchases then I would limit time spent. I've seen some people's collections have total transformations and I hate to say it but I worry about them and the influence tpf has on them. I can't help but feel that some people who get a little out of control with the buying are trying to fill a void.
It's like anything, you start running with a certain crowd and adopt their behaviors, the sayings they say and develop similar tastes. But here you run the risk of depleting funds, even if you have the money accessible, and even it that's not an issue, if a person would have invested that money instead of dropping tens of thousands on bags they would have even more money. I know people say it all the time that LV is a good investment, and it's true it has resale power, sometimes double what you pay if it's mint and new that is. There is nothing as valuable an investment as money itself. Money makes money, bags don't make money, lol.
I think the healthy thing to do is to just make a list and keep a timeline of when you want to make purchases this way your spending pattern isn't altered from the way it was prior to tpf. For me since I would be adding a bag regardless of being at tpf, tpf is helpful to me bec. I'm exposed to things and contemplate bags that I wouldn't have given a second thought, but I still wait the time period that I would have ordinarily waited. I don't see a bag and run out immediately to add it (I have waited a year for a bag) and I try not to obsess over it and enjoy what I have in the mean time. I find I get the most ideas for bags in the celebrity section, bec. they are modeled there.
