As a Tarot reader, ask yourself: Do you have a field of knowledge that is useful to others? Like, I was a very skilled court reporter in a very challenging locale (south Florida in the Miami Vice years, owning the office and having mainly lawyer clients who represented banks or major criminals, usually drug related ones. So I can read lawsuit material in detail and nuance, and the same for medical material because that too is the subject of lawsuits.
So if you have such a field of knowledge, ask Tarot questions in that subject, and find which cards relate to which parts of it.
