Have an Answer?
Ask and answer these questions:
1) Do you like people?
2) Do you have a lot of patience?
3) Have friends and family regularly told you you're a "good listener?"
4) Has anyone ever told you that you "give great advice" ?
5) Has anyone ever described you as a "warm" or caring person, as opposed to "cold and distant" ?
If you can answer "yes" to all 5 of those questions, then you could be a good candidate to be a professional coach.
