There's a lot of truth to the "depressed artist" stereotype
Given all this, and given what you likely know about famous creatives, you can see why self-generated thought and neuroticism can lead to both creativity and unhappiness. When your brain constantly churns out hypothetical scenarios and narratives, reality (whatever that is) may not take precedence over the scarier, more disastrous plotlines. Maybe you're a ball of anxiety, but maybe you'll also turn that anxiety into "The Scream."
To think, some people are just rational from the get-go! I always envied and wondered why my laid-back friends and my level-headed sister who works in data don't sweat the small stuff… or, you know, get stomachaches over tardy text messages. Then Dr. Perkins explained it perfectly:
"Cheerful, happy-go-lucky people by definition do not brood about problems, and so must be at a disadvantage when problem-solving compared to a more neurotic person. We have a useful sanity check for our theory because it is easy to observe that many geniuses seem to have a brooding, unhappy tendency that hints they are fairly high on the neuroticism spectrum. For example, think of the life stories of Isaac Newton, Charles Darwin, Vincent van Gogh, Kurt Cobain, etc. Perhaps the link between creativity and neuroticism was summed up most succinctly of all by John Lennon when he said: 'Genius is pain.'"
