How To Become A Life Coach And Self-employment/consulting/contracting Jobs - Share Ideas

Hi all,

Looking for answers for two questions (for different reasons, so please requesting not to combine both)

1. How to become a life coach in USA? Any exams/certifications needed?

2.Please share your ideas regarding the topic which are good for a women based in USA. As the person is not really comfortable facing public, please suggest more of back-end roles not having to deal with the customers.
