>But across many professions (medical doctors, researchers, professors, ...), people are actually interested in their work! I'd be very confident that if you psychologically assessed people in those fields they'd almost all be in the top 10% in conscientiousness. Those people feel uncomfortable every hour in which they aren't productive. They work all the time because that's how their brain works and that's what the job demands. That doesn't make them happier. People high in conscientiousness don't necessarily feel good from working a lot, they rather feel bad when not being productive. I invite you to look up statistics about drug usage among medical interns.
