Now, I make all sorts of general lists, I probably have twenty-five on my iPhone, but they're more suggestions than firm directions. I walk around Costco consulting the lists on my phone. (I notice I'm not the only person doing this, and lots of them are much younger than I am.) But I'm always ready for inspiration. Being ready to buy things not on the list has worked for me, although I know it's against some financial planners' advice.
Do you make lists? How detailed? Do they work?
