It's reasonable to suggest that certain folk have a greater capacity to work longer before burnout. However, that choice will always come at a cost, depending on your current position in life. If you are a young single individual this may work for you well and you may get ahead to a certain extent, at the expense of other fruitful activities that would enrich your youth and allow to develop into a well rounded individual. If you are married and have a family, chances are your lifestyle will seriously impact your family life. The other point to consider is that work longer does not mean working smarter. I would chose the latter, and I personally work hard at finding ways to be smarter at what I do without working 15 hour days. I also believe that outside activities, other hobbies, socializing provides less obvious but valuable benefits to your skill.
