I like the insight of luck combined with incredible talent. Too many people get a bad taste in their mouth by leaders who only attribute success to hard work and dedication. Knowing what battles to really fight and die for is a talent in and of itself, but it's also a bit of luck to both have access to systems to allow you to impact important projects and also to end up impacting the right ones.
It's very frustrating to be able to have a massive impact, but not get any sort of notice for it. Many people just start punching a clock when that happens. I've done it.
