Of course all of them are very very interesting,
may be there are some of them that can be cosidered with more priority to learn or get the information

Yikes, tough question Laura. Everyone who has taught a workshop on PA has been or is currently a mentor of mine. I think they are all valuable. It would be helpful to know what interests you most. What are most challenged by when a client comes in to work with you? How do you learn best? Do you like areas of technicality or areas that address concept and allow you to interject yourself more confidently. If you can answer some of these questions I'll do my best to guide you.
