I can identify with these "maximizer" characteristics...however, my friends and family have always pegged it as "indecisiveness" for me. I take forever to make desicions, especially about buying things, because I want to make sure I'm getting exactly what I want and need.
The best example I can think of right now is that I was shopping for a neutral-colored skirt for work. I've gone to probably 10 different stores looking and not found a good one yet. But, when I find one that "might" work, I have to examine it from all kinds of viewpoints: do I like the cut? does it fit me like it should? are there any imperfections? is it something I would actually wear? will it go with the style of my shirts? what kind of image of me will it portray? is it too expensive for the quality it offers? might there be something better out there?
So, all these things are going through my head while I'm in the dressing room and if a friend is with me, they're like "just get it, let's go, you can return it if you want" (which I rarely do) because I usually don't get it unless it's exactly what I wanted.
Anyhow, for this reason, I generally prefer to go shopping alone, so I can take my time, though sometimes I wish for a second opinion. I've also started sewing some of my own skirts - just the cute casual summer ones, since I can never find what I want in the store.
