What are some small things you've done in your life to create happiness?

I have decided that new to minimalism I have been removing things to make my life more simple but now I'm thinking of things that I can add back into my life. You know, the things that create joy that are actually important to me. I've made a list so far of flowers every two weeks, wearing my hair natural, and books from the library. I want this life to be a place I enjoy and by doing this I think I can make that happen!
