If you are looking to build and launch breakthrough products, you don’t need to be reasonable; you need to be unreasonable. Being reasonable keeps you in the realm of incremental innovation, adding small new features and functions to a product until it gets so complicated and unwieldy that a whole industry has to be built around it (Microsoft Windows and Office, anyone?) No, you need to be unreasonable like Steve to make breakthrough disruptive ideas. You need to push the envelope, push yourself, and push your teams to do more. You can’t just step back and relax. No one ever built a massively huge new industry or company by being reasonable. You need that immense drive to succeed, the energy and passion for moving forward no matter what detrimental things occur, and the skills to make them happen (or at least partner with those with the skills).
