Watch Your Head on the Ceiling
Do not believe you can predict the future, and balance data with experimentation instead. Do not choose big over fast, especially because timing is everything in business, and a bloated idea might arrive to market too late. Do not mistake managers for innovators, as one does not guarantee the other. Do not let your ambition overshoot your capability, and employ experts to help you execute your ideas. Do not start big ideas at the center and let it fester out; allow good ideas to pop up in the periphery (via things like skunk works) and make gradual changes for the better. Do not listen to the wrong customers, lest your business end up a big fish in a small pond that is only small because it dried up. Finally, do remember to connect the dots, finding innovation in the big picture.
