Everyone who makes $400k/yr is an outlier to some degree, regardless of their pedigree or employer. The key to my success is a skill stack, rather than a skill. I'm a pretty good programmer but I am really good at taking really complicated things and explaining them to non-technical people without using jargon. That makes me valuable where I am. But the thing that opened doors for me is the third leg of my skill stack: teaching. Every opportunity I have to teach something, I do it. It can be teaching my entire team about unit testing and mocks, how to transition from one source control system to another, or taking a junior programmer and teaching them to think like a programmer. Especially the latter group, those people who you teach to improve their own careers really remember it. Because employers suck at giving major raises/promotions when people grow, those people usually leave. And then every opportunity of theirs suddenly becomes your opportunity too. As soon as there's another opening, they want you on their team. In a way, you increase your own luck by increasing the luck of others.

Of course it's not 100% guaranteed, and if you acted as if people you mentored owed you something they would just resent you anyways. To butcher a metaphor, when I changed from being a shooting star super-developer to a rising tide that raises all ships, that's when my income and opportunities really took off. When I stopped caring about getting credit for everything I touched. When I started doing everything I could to help others in their career, mine really took off.
