How do you approach wishlisting?

I use a wishlist (a folder of bookmarks) to try to curb impulse buys, but I’ve noticed something - half the time, I look back and find that certain polishes have lost their appeal to me so I remove them from the wishlist. Other times, I obsess over something for months before finally caving. I wish I could say that my wishlist purchases are all satisfying and amazing, but sometimes I still end up buying wishlisted polishes that just don't do it for me. So, how do you approach wishlisting? Do you have a system that works well for you?
