Take the counting thing even further and you'll start sorting them without meaning to. Like you'll catch yourself making a little stack of the ones that are "too pretty to read" vs the ones with actual recipes and then you realize you've basically made a whole system. My mom did this with cookbooks and now she has them by season and mood. It starts as a joke about your brother being annoying and ends with you alphabetizing by coffee table size. Good luck going back now that the counting has begun.
