The following is an excerpt from the CoachStart Manual.

If you don’t enjoy seeing and being part of someone’s growing, then don’t become a coach.  If you don’t get a kick out of being part of someone learning something new, bursting through a barrier, having FAR more than they ever thought they could have then this is not the career for you.

Having said that, I don’t believe there is a human being on the planet who couldn’t learn to enjoy that!
