How do new/developing/experimental therapeutic activities relate to regulation of psychotherapy and counseling?

When these activities (like Life Coaching, e.g., but others) look a little like psychotherapy and spirituality and talk about people's lives but do not diagnose disorders, are not researched or taught academically, and are not well known. Is it alright for an interested person to study and begin practicing these without licensing as a psychotherapist? As long as it's not a recognized psychotherapy?
