In the Zone of Excellence are the activities you do extremely well. You make a good living in your Zone of Excellence. For successful people, this zone is a seductive and even dangerous trap. To remain in this zone is to hobble yourself from taking the leap into your Zone of Genius.
The Zone of Incompetence is made up of all the activities we’re not good at. Others can do them a lot better than we can. Surprisingly, many successful people persist in wasting their time and energy doing things for which they have no talent.
Establishing a habit of excellence begins with a core commitment to set a standard that scares the daylights out of you. Some people think excellence means being as good as the next guy.
Don’t use average to estimate the limits of excellence. You will drastically underestimate what is possible. Focus on your best performers, and keep pushing them toward the right edge of the bell curve.
