I know someone like that, who just graduated from medical school. It seemed to be all about the hours you sink into it. Whether it’s clever work or not doesn’t matter. It’s hard and hard equals productive. Many other fields are also hard to succeed in, but it seems like just putting in the hours is the worst possible way to go about it at a certain point, because thinking about what you’re trying to accomplish is a much more useful exercise.
