I'll get around to picking the cookbook later.
I'll add, though, that about three years ago, I went from maybe 30 cookbooks down to three. I had cookbooks I'd had for years and never cooked from, and it was actually starting to give me some anxiety. Every time I'd go in the kitchen, I'd see the cookbooks there, and I'd start to think about how I'd better hurry and cook at least one thing from this or that cookbook, and it just started to feel like a lot of stress and pressure all the time. I'd wake up in the middle of the night sometimes, thinking, "Oh crap! I said I was going to make something from that Amish cookbook this week, and I haven't yet!" and I'd have to get up at 3AM or whatever and at least pick out a recipe.
Now, though, I'm up to about 10 cookbooks again, so I have to do a purge again shortly, before the cookbook gremlins take over.
