Pilot Unknown. I don't understand, if you are so dedicated and so much want to fly for a career, why have you not completed your PPL? Why have you not already done your exams, or an instrument rating, or at least got some PPL and post-PPL hours under your belt? Why not start again, get your PPL done, book yourself in for your ground exams and medical, then make your decision.
You will know by then if it is the career for you.
