If you are interested in coaching people/teams/organizations and subsequently helping them overcome the various professional and personal barriers that stand tall in their way to success and fulfillment, you need to understand that mere benevolent intention will not prove to be effective when it comes to enabling you to realize your potential as a life/career coach.
It is imperative to have a credibility factor associated along with this intention that stands as proof of your skill and commitment to excellence in coaching and provides you with an edge over the others in the same field.

This would ensure that you not only develop an accountability factor but would also enable you to enhance your skills as a coach.
