A comfortable routine can turn on us, leaving our creativity stifled, dulling us to other possibilities. We become lethargic, sleepwalking through life. Boredom soon nips at our heels.
At the other end of the experience spectrum, we have bungee-jumping thrill seekers. Tired of sexual escapades and rock climbing, they sometimes self-medicate to starve off boredom. Drugs can stimulate many feelings: euphoria, depression, anxiety, even fear. But none induce boredom (though some, like cocaine, can leave the user with a devastating boredom, after the drug has done its thing). Sex, food, drugs, and gambling each stimulate the same dopamine reward pathway in the brain.
Psychologists tell us the cure for chronic tedium is not high-sensation thrills. Somewhere between boredom and anxiety there is a sweet spot called flow. It's an optimal level of arousal. As Dr. Richard Friedman writes:
Flow happens when a person’s skills and talent perfectly match the challenge of an activity: playing in the zone, where there is total and un-self-conscious absorption in the activity. Make the task too challenging and anxiety results; make it too easy and boredom emerges. Flow get to the heart of fun. It’s not hard to see why the enforced tranquility of a Caribbean vacation could be a dreadful bore for a workaholic but bliss for a couch potato: temperament, as well as talent, have to match the activity or there is trouble in paradise.
