If I worked 100 hours weeks I'd go nuts in very short order. I'd hate it. I've known at least one person who has probably worked 100+ hour weeks for most of his life. This person has a wife and a son, and he hates them. Well, perhaps not hate, but he certainly avoids them most of the time. If you tear him away from work for something, he'll insist on talking about work. If you go to a conference with him you can see him slowly going mad being separated from work for such an extended period of time, even if it's to talk to other people about work! He loves what he does and is ridiculously happy doing it, but that's all there is to his life. Retirement will kill him. He is very accomplished, but there are people who work 20 hours a week out there who are more accomplished. Don't listen to people who tell you that you'll burn out if you work X hours or be a failure if you only work Y hours. Human beings are variable. Find your optimum.
