I'm purging, too. I'm not sure yet how severely. We move back to the States this summer, into a much smaller house, and I have to pack for one trip there after accumulating books over three trips here.
I was showing my husband a great book I have and asking him he thought a certain friend of ours here could use it. He agreed that it looked good and asked, couldn't I use it? I said I could. BUT .. It has been my habit to make decisions based on what I "could" do, what I would like to do—I need to make decisions based on the reality of what I actually do. The reality is that I have owned this book for years and done nothing with it but crack it, flip through it, and move it from one shelf to another, one continent to another. And it is literally weight—and I feel the burden of it not just as I load up suitcases but psychologically as well. My obssession has left me very scattered, and I feel two years of tiredness in my brain. I need, weight limits aside, to travel light this trip.
