"...And we’ll look to David Bowie for some instruction here. Bowie, at the end of his career said, “When I look back at four decades of all these characters I’ve had, from Aladdin Sane, to Thin White Duke, to Halloween Jack, to Lazarus, I see that at the core, I’m a songwriter and I’ve written about three or four themes my entire life, things like loneliness, isolation.” And I think that’s really instructive because when you think of Bowie, you think of someone that is constantly changing, don’t you? And both Madonna and Lady Gaga have said they took that same blueprint. But actually what’s happening is you have an example of somebody who really understands their core, understands what they’re good at, understands what they’re passionate about, and then rotates the collaborators, the cast of characters, the ideas around that core idea. So getting to your core is actually the secret to being able to change." (HBR IdeaCast)
