My purpose question

I have known for quite a while that my purpose is:
I am a light bearer for my family, friends and the world.
My question is: how do I know what to do with it? I love on my family and am very blessed. I help people in practical and spiritual ways. I encourage everyone who is down or sick. I am a coach, and wonder if I am to do it to help people and get paid or do it as a gift to others and not worry about niches, programs, products, etc.?
