If you think you have problems, just take a look at the story of Nick. He’s a gifted piano player, but also has suffered from Tourette’s syndrome since the age of 7. This 49 minute documentary looks at the link between madness and creativity. The main message is that there are no hopeless cases, even for people with Tourette’s syndrome. Another message is that an increase in dopamine may also increase the drive to create. Although dopamine can be purchased over the counter, too much dopamine can make you paranoid and delusional.
