One more thought about the echo chamber
If you're defining yourself and your business in terms of your competition, you're living in the echo chamber. Companies and organizations don't grow fast at the expense of existing competitors. They grow fast for reasons that have nothing whatever to do with whether your service is 5% better or your product is a little more convenient.
You don't beat McKinsey with better consulting advice, you don't raise more money than the United Way by spending it more efficiently, and you don't sell more widgets with a slightly longer guarantee.
