Gotta be more to the story than you have told. It doesn't seem as the instructors, Etc. are the problem any longer; as you say you're making progress now? People generally know what motivates them, sometimes not. Are there outside/personal issues? Have you told your instructor of this issue? They might be able to help. Do you have a plan for your life, goals, Etc? Or is flying just something you wanted to try or that seemed interesting? Are you paying for it or is someone else. Especially if someone besides yourself is financing this endeavor, you owe it to them to solve the problem quickly or stop. You might think about letting your instructor in on this. Good luck...
