"In business, the only thing that counts is results, not how hard people work or how many hours they put in. Have you noticed in your startup or around your office that some people are always at work and busy, but others seems to consistently get more done? Studies of software teams, for example, show differences as great as ten to one in productivity between working team members.
Much has been written about the external influences of office environments, motivation, and personal health impacts, but I see evidence that there are personal productivity tactics that contribute just as much. Along these lines, I just finished a new book, “The Productivity Project,” by Chris Bailey, who conducted dozens of interesting personal productivity projects on himself."
