I recently saw the movie Inside Out, an ambitious Pixar flick that tackles the subject of emotions and how the brain works in an animated feature. The main characters: Joy, Sadness, Anger and Disgust rotate their positions at the “controls” of Riley’s brain and manipulate how she is feeling at the moment.
The movie makes it appear that emotions happen to Riley: because Joy is in charge, Riley is happy and so on. But in reality, you are the one at the console. You can choose how to respond to events and what emotions to express.
Inside Out is a delightful and entertaining film. Just keep in mind that it is a movie, and that you can direct your own story as you wish it to play out.
