1. Turn on this song. (Or any song that's REALLY good to dance to) 2. Turn it up. 3. Dance. (Not the way that you akwardly dance at parties- go ALL OUT. No one is watching so who cares what you look like.) 4. If mood has not improved, repeat.
**Testimonial: this little trick has fixed many a bad mood for me. I don't think anyone will EVER see me dance like that in public, but it is an instant pick me up. Hoorah.
