Coaching by itself is a great tool, but there is a big cliche in the coaching business.
People who had never been great at someone or have so little brand themselves as coaches for greatness or coaches for abundance.
It is really ironic. Those wannabes might actually do more harm than good. That is why it isn't a bad thing to start and to walk the path of the beginner, but in this profession, it might be better to have a supervisor.
As with every profession working with people, you need to walk the path yourself before you are able to do it to others.
Guess what, many coaches are not doing that. That is why be very careful when a coach approach with a shiny site and lack of credentials.
