I have helped many life coaches build very successful businesses - the key issue is being able to solve problems people will pay you for. I've found that the more specific you can be in the type of problem you solve (do you help midlife professionals with second careers? or college graduates to position themselves for their first job?) - the better you'll do.

The steps for getting there:

1. Do some research - find out what problems people are having - that you can help them with.
2. Create a small scale offering and test it out with people you know who are willing to pay you a little bit for it.
3 Start building a community around it.

Best of luck with letting your brilliance shine through in the world!
