One of the most interesting things about touring is how separated you become from the "stuff." And shopping. When you have to ask, "do I want to carry this around for the next two months?" it keeps the urge to buy at a minimum.
I've been packing back up, and other than the mail that got out of control for the month I'm here (ads that expired before Christmas, and catalogues for clothes I can't afford crept into every drawer and crevice) I didn't bring a lot with me, and didn't buy things once I got here. There is something nice about knowing exactly how much in life you really need, and what are luxuries. On tour, luxuries are scented lotion, ear plugs, a sleeping mask, and a good pair of chenille socks. A portable CD player can change from luxury to necessity depending on the day, and how much you need to pretend there's no one else around for a minute.
We've all figured out by now that stuff doesn't make you happy, and those that have everything are miserable (and if you haven't, come work here and get first hand experience).
Of course, saying this, I have a storage unit of stuff in Texas that ONE of these days I'm going to have to drive down and move to wherever I decide to settle....
