Well, it's like a doctor or a pharmacist really. You're not paying them for the relationship as such, you're paying them to help you. So you should go to the T with specific ideas that you want to discuss and find solutions to. It can save a lot of time and money knowing what you would like them to help you with. It's a case of staying focussed on your goals with them, and not veering off on wild speculative chit chat all the time.
