I'm annoyingly obsessive in general, so whatever I'm thinking about is intense at the moment, but not constant. So if I'm reading, don't ask me to make dinner; if I'm climbing, I'm totally focused on my next move; if I'm shopping, I will not rest till I find what I want. I probably think about clothes more than I should, but not more than I used to - but now that I've found YLF, I think about fashion and clothing very differently than I used to...
It's like how I learned to play blackjack - once I learned there was a basic strategy, I worked hard to memorize it, so I eventually did NOT have to think about what to do. It just became reflexive somehow. (No, I'm not a serious gambler - though I could easily be one!). I'm hoping to incorporate some of that basic strategy into my shopping habits, and right now, it's taking time and effort. BUT SO MUCH FUN!
