Show Stopper!: The Breakneck Race to Create Windows NT and the Next Generation at Microsoft

There's a book called Show Stopper!: The Breakneck Race to Create Windows NT and the Next Generation at Microsoft by Zachary, G. Pascal The book itself is pretty interesting but there's one line in there about how Dave Cutler always takes his vacations on time, every time without question. It never goes into any more details but that seemed totally at odds with what I expected? At least when hustle culture and the idea that leaders don't take breaks seems somewhat prevalent nowadays (or at least in the mid-2000s) As someone whose parents don't take vacations all that often, and came from a small town where there's that sort of "I'm a good person because I work harder than you" mentality, I was kind of hoping Cutler might reveal his philosophy of why he takes holidays without failure. Maybe he just likes holidays and I'm over thinking it haha
