I have a few items in my todo thing for certain categories of stuff: spices, detergents, etc. where I keep lists of "nice to have" stuff from this category.
And when I go to a store selling this type of stuff, or order something from this category online, I just consult these lists. Might seem overly bureaucratic, but it saved my ass more than once. So why bother thinking what it feels like when it just works!
