The next time you're in a bad mood, try pulling up some Amy Schumer or an SNL digital short on YouTube.

Listening to upbeat music can actually improve your mood. 

It's important not to overthink, "Am I happy yet?" while listening, and instead just allow yourself to enjoy the experience.

Just the illusion of order is enough to ease the mind. Put things into neater stacks and piles for an instant boost in mood.
