Regarding the last bit, it's not terrible advice. One of the big differences between Silicon Valley and elsewhere is that there's a much bigger focus on positive-sum activities here. (That's in contrast with Wall Street, which has a zero-sum focus, or places like Florida, where it shades negative-sum.) It's a useful attitude when you're trying to create monster new businesses from scratch, because it's much easier to disrupt an industry or create a new one if you're creating massive value.

Google's a great example of that. They have made the world enormously better, and profited greatly thereby. Their profit is a small fraction of the value they've created. And that's why they won. Their competitors got greedy, and wanted a much bigger share of the total value created.
