All start with a PPL. Now I am ATPL and fly biz jets. I never worked as hard as when I flew pistons. As you go up the aircraft ladder it gets easier and easier with reference to good kit and stable a/c. FL350 is much more relaxing than 3000 ft. If you have a PPL be proud of it, I would hesitate to jump in a 172 and fly away today. I need instruction, from a PPL.
