Well, no. I've been reading this book about the daily schedules of the greats [1] and there are many artists who had very active social lives while in their prime. Some more so than others - Francis Bacon would wake at 7am and work hard until lunchtime, when he'd share a bottle of wine with a friend in his studio and then drink, eat and party until the middle of the next morning, getting to bed at 3am. Rinse and repeat.
