There are direct paths to a successful career. But there are plenty of indirect paths, too.

How can you make sense of the future when you only have data about the past?

The personal computer was a disruptive innovation relative to the mainframe because it enabled even a poor fool like me to have a computer and use it, and it was enabled by the development of the micro processor. The micro processor made it so simple to design and build a computer that IB could throw in together in a garage. And so, you have that simplifying technology as a part of every disruptive innovation. It then becomes an innovation when the technology is embedded in a different business model that can take the simplified solution to the market in a cost-effective way.

You may hate gravity, but gravity doesn't care.

Disruption is, at its core, a really powerful idea, but everyone hijacks the idea to do whatever they want now.

If you ask the average guy on the street to name five companies that have truly transformed themselves over the few decades, Hewlett-Packard would be on everybody's list. You'd also put on this list GE and Johnson & Johnson.

Year after year after year, people write books about managing innovation or about leadership, for example, without ever going through the pain of saying, "This kind of leadership will cause this result in these circumstances and a very different result in those circumstances." This is academic malpractice of the worst kind.
