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

When product performance outstrips the ability of customers to use that performance in an industry, the competitive game changes. Under those circumstances you have to decouple components businesses from assembly businesses.

Motivation is the catalyzing ingredient for every successful innovation. The same is true for learning.

The biggest mistake is an over-reliance on data. Managers will say if there are no data they can take no action. However, data only exist about the past. By the time data become conclusive, it is too late to take actions based on those conclusions.

The mistake managers often make is defining their industry too narrowly. Digital's market share in the minicomputer market stayed very robust even as it fell off the cliff. Disruption seems to come out of nowhere, but if you know what to look for, you can spot important developments well before the market does.

History is littered with great firms that got killed by disruption. Of course, the personal computer, a technology that first took root as a toy, got Digital Equipment Corporation. Kodak missed the boat for a long time on digital imaging. Sony was slow to get MP3 technology. Microsoft doesn't know what to do with open source software. And so on.

I've concluded that the metric by which God will assess my life isn't dollars, but the individual people whose lives I've touched. I think that's the way it will work for us all. Don't worry about the level of individual prominence you have achieved; worry about the individuals you have helped become better people.
