Ah ah ah I do something similar, sometimes I pick them but I use different tricks, I try to select two or three in the bookmarks (where the numbers are less overwhelming and I can be more certain it is a recipe I will like), two or three in non indexed books, and I buy the ingredients to make them on any given day in the next 10 days or so, but without assigning a day to it or fussing too much if I skip one as long as I do most of them
To ease out prepping I sometimes do my recipes in two steps, cut the vegs and similar in the morning, eat something easier at lunch and then on the evening all the cut and prepping is already done so all I have to do is the actual recipe
It varies though! Recently I have a lot less time to cook in Paris,with my new job very demanding, all my cooking ustensils stuck in London (just what little there is in the flat I am renting and what I couldn't live without buying again), and additionally the food offer is so great here that sometimes you don't even want a recipe (for example my butcher accross the street is exceptionnal, so you really just want the meat, not too much prep around except maybe for the side), or, there is a lebanese takeaway where you just buy these delicious dips like hummus, labneh etc and just eat with a galette type bread, or just cheese platter and ham would do with a side salad. As a result I plan a lot less maybe just one or two recipes at any one time
