From Seth Godin:
If you enter a conversation looking for something to test, measure and ultimately change, it’s likely you’ll find it. That change makes you more competitive, and you continue to cycle past your competitors. On the other hand, if you enter a conversation concerned about maintaining the status quo, it’s likely that this is exactly what you’re going to do.
Some people read business books looking for confirmation. I read them in search of disquiet. Confirmation is cheap, easy and ineffective. Restlessness and the scientific method, on the other hand, create a culture of testing and inquiry that can’t help but push you forward.
