Let’s start with a few definitions :
MENTOR
Mentor is a person with considerable experience in the same or a related field of life or business that you are in. You meet, you talk, and he (or she) can simply advise you on something based on his (or her) own experience, and, if necessary, back it up by consulting his (usually wide and valuable) network of contacts.
COACH
The main difference from a mentor is that he (or she) doesn’t have to know exactly what you’re doing. He doesn’t have to, because a coach doesn’t give advice, but instead asks wise and skillful questions. He or she does it in such a way that you yourself arrive at the right answer that is in line with you and your values, which is somewhere inside you, in Bohemia. And finally: the coach is screwed because of the ongoing spoiling of the market for these services by people without good education, experience and aptitude. Unfortunately, sometimes admitting that you are a coach is a real shame.
