Working long hours goes with the kind of person you are. 80 hour work weeks may be productive for some people whilst others perform better with 37 hour work weeks (or less). We are all different.
Something to keep in mind for this, is that people tend to be fairly lousy at detecting how what they do affects their productivity. Even if you think you do well with long weeks (or multitasking, or whatever), you can't know that without keeping a log of how much you actually got done under which conditions.
