I love it when I finish up a beauty product

I love cosmetics, so of course I have a lot of beauty products. And when I have so much stuff, it's not often that I use up something and can throw it away. Often, I forget about what I have and never get to get the full use from it. So when I do completely finish up a product, after using all of it up, I feel a sense of accomplishment. It might sound silly, but I love that satisfaction of knowing I used all of it. And if I did use all of it, that means I really liked it and it worked for me. And what's better than that?
