Always with these New Obsessions

Every few months I end up getting obsessed with something. In the past it's been sudoku, makeup, hair stuff, all types of brushes, and shirts. I've never really had a shoe obsession. I think that female gene passed over me.
Right now I am obsessed with nail polish! My nails are so brittle that I kind of have to paint them unless I want them to start flaking off or cracking in the weirdest spots. My nail polish collection isn't as large as some people's but since it is so cheap I can see my self having a huge collection.
Because nail polish is so cheap I am afraid this will get a little out of hand. I've already ordered enough nail polish to double my small collection.
