I have a lot of bath stuff, like Soap, bath salt etc. I also put some books, one on dinosaur art, one on silk painting. I have a couple of toys like squishy foam and a magnetic art thingy. I have some photo books from the last few years with my family and bf. It’s actually a little sparse right now but another good thing to put in is gift cards...ie visit Starbucks or iTunes ...new music is a must when you’re feeling down. At one point I had a new pair of silky pjs. Anything that makes you feel good is fair game. It’s important to fill the the box when you’re happy and use it when you’re not. If you wait nothing will seem particularly interesting or fun....but if you fill it up when you’re a little hypo or something it’s like delayed retail therapy.
