長時間働くことができるのは独身だからです。家庭を持つと、自分の時間はすべて自分のものではなくなります。Macチームのほとんどは20代半ばで、ほとんどが独身だったため、事実上、人生をそれに捧げることができました。

Working long hours being single helps because your time is yours. Once you have a family your time isn't all yours anymore. Most of the Mac team, we were in our mid-20's, most of us were single, and we were able to essentially devote our lives to it.
