Yeah. I think the discipline of trying to get rid of a certain fraction of my books helped me focus on making the choices. For instance, the last two cookbooks I bought were gluten free/quinoa books, and after some wrestling with myself, I decided that if I was buying more gluten/wheat free books, surely I could let go of at least one of the vintage (wheat) flour cookbooks. That just sit on the shelf, a collectable I never even open, because it's nowhere near the most interesting of my old cookbooks.

But yeah. The choices can involved some self-reflection for me, on more than just the book at hand. (Like - Am I really committing to changing my habits around wheat?)
