There are many people who call themselves career coaches today. Some bring great credit to the profession and others are nothing more than manipulative con artists. The knowledge, experience, style and personal characteristics of a coach are very important.
A coach must bring a special kind of knowledge to the situation. It’s one thing to sit in a classroom and listen to a professor lecture on some arcane subject. It’s quite another to learn archery with an instructor standing beside you, guiding your hand as grasp the bow, and pull the arrow back as you line up the target. A professor imparts knowledge, often quite useful, while a coach rehearses you in the action steps of a discipline.
