The signature of mediocrity is not an unwillingness to change. The signature of mediocrity is inconsistency.

The only way to remain great is to keep on applying the fundamental principles that made you great.

Change your practices without abandoning your core values.

Perhaps your quest to be part of building something great will not fall in your business life. But find it somewhere. If not in corporate life, then perhaps in making your church great. If not there, then perhaps a nonprofit, or a community organization, or a class you teach. Get involved in something that you care so much about that you want to make it the greatest it can possibly be, not because of what you will get, but just because it can be done.

The start of the New Year is a perfect time to start a stop doing list and to make this the cornerstone of your New Year resolutions, be it for your company, your family or yourself. It also is a perfect time to clarify your three circles, mirroring at a personal level the three questions... 1) What are you deeply passionate about? 2) What are you are genetically encoded for - what activities do you feel just "made to do"? 3) What makes economic sense - what can you make a living at?

In an ironic twist, I now see Good to Great not as a sequel to Built to Last, but more of a prequel. Good to Great is about how to turn a good organization into one that produces sustained great results. Built to Last is about how you take a company with great results and turn it into an enduring great company of iconic stature.

Not one of the good-to-great companies focused obsessively on growth.
