So the hardware that is your brain is a dual core processor, but it's running a pretty rock solid OS that's able to coordinate threading and task scheduling fairly well without any noticeable lag time.

No one is forcing you to work those 80-120 hours a week, except yourself.

I find that when you're working on a project you actually enjoy (and you're young with nothing better to do), you willingly go in on weekends and stay till 8 or 9 o'clock to fix that one last issue.

It's just a balance. If you enjoy your work, spend the time. It's fun! If you don't like it, work 3 hours a day and fart around on the 'net looking for a job you like!
