Actually, Laurel, it's not that you want stuff that you don't have, but that you want stuff that you think you don't have.
And the best way to change this is to begin thinking that you have it.
As in, "Oh, there's my electric, fully-loaded, Habitron Cloud Maker!!"
Rain, please -

The same goes for wanting to be the kind of person you think you aren't, Laurel, living the kind of life you think you don't have, and having the kind of friends who don't think you're really, really "out there"... unless you're cool with the latter, which I think suits you.
