Help when you are stuck
You don't read many self-help or management books before you understand what you "should" do to be successful in anything you do: focus, work hard, affiliate and keep your integrity. That and a bit of luck should just about get you there.
Yes, but. An Enneagram coach understands why you don't, and in one sense, can't do the things you know you should do. Take something as simple as focus. An Enneagram coach knows that whatever your conscious focus is, you have a powerful rudder just below the surface of your awareness that has its own focus.
Life can be hard. That's why it is interesting. A coach can support you, gently re-direct you and help you with your self-understanding. From an Enneagram depth of self-understanding (and understanding your boss or spouse or banker) you can discover more options and resources than you have all by yourself.
And the best part is that when I do my job right, you will be convinced you did it all yourself and you and everyone else will give you full credit for your success.
