I'd highly recommend Adam's book, Originals, that this article derives from. This article, though, focuses on one aspect that I think it particularly important: how to hire people who will help shape your organization, preventing it from getting stale or dogmatic. One of my favorite pieces of advice: "two weeks before her interview, give a candidate three names of colleagues to reach out to learn more about the culture. Tell her that when she comes in, you want to know what’s working and what needs to be changed." This is an interesting interview technique that also helps the organization get feedback from a different perspective.
