Good is the enemy of great. That good is the enemy of great is not just a business problem. It is a human problem - James C. Collins

For no matter what we achieve, if we don't spend the vast majority of our time with people we love and respect, we cannot possibly have a great life. But if we spend the vast majority of our time with people we love and respect – people we really enjoy being on the bus with and who will never disappoint us – then we will almost certainly have a great life, no matter where the bus goes. The people we interviewed from the good-to-great companies clearly loved what they did, largely because they loved who they did it with.

A culture of discipline is not a principle of business, it is a principle of greatness.

It is better to first get the right people on the bus, the wrong people off the bus, and the right people in the right seats, and then figure out where to drive.
