The other key thing about the Fortune article is that Brian Chesky decided to take his mentorship up, not sideways. I see a lot of emphasis in startups on peer groups for support and learnings, and although peer groups are great, you won’t learn something if your peers haven’t yet experienced it, and you certainly won’t get the depth and breadth of knowledge from more seasoned mentors. Brian Chesky went to Warren Buffett, George Tenet, Sheryl Sandberg, the CEO of Disney and Jony Ive chief design officer at Apple.
