Happy box

I think when I find the free time, I'm probably going to make a happy box. It's something I keep meaning to do but keep putting off. I think it would be a nice thing to have when things get tough. It's a healthy coping mechanism I'd like to start using. I think it would have to be digital though, because I don't have many possessions. Maybe pictures of friends and family, things I like, stuff from childhood, stuff that brings up good memories.
