I think there must be a nice middleground between your position and Sivers'. Even workaholics have periods where they need to spend a day reading a book or a weekend camping. In their case, they're just burnt-out somewhat, and need some "recharge" time. They know that they'll be ready to work again soon. Others are lazier by nature, and would spend the majority of their lives doing little or nothing -- and that might include traveling, gardening, reading, playing video games -- and they do need to push themselves if they're going to accomplish anything ... if they want to accomplish anything.
