You might want to consider purchasing Eric Bolvins, Arban Manual. You could work through the lesson plans in it with your teacher. He could make sure you do the exercises correctly and decide when you should progress. Each lesson is broken down into 5 or 6 sections. I also am a comebacker who found a teacher. I was also disappointed in the lack of structure I got. I ended up not continuing (because of the time commitments required). However, if I were to re-start with the same or different teacher, I would consider using the Arban manual to provide some structure. Best Regards and remember Festivus is Dec 23.
