I've been thinking a lot about innovation lately. It is a form of "thought leadership" ... intuitively identifying the underlying issues and figuring-out the best things to do, now, to transform the situation and create new possibilities.
To paraphrase Peter Drucker, innovation is a tool that transforms challenge into an opportunity for a different business or service. It is capable of being presented as a discipline, capable of being learned, capable of being practiced.
Learning and innovation go hand in hand. It is often folly to think that what you did yesterday will be sufficient for tomorrow. This is a close cousin to the idea that "you are either growing or dying."
