But don't expect to work LESS than 40 per week if you want to be successful.
At least not at first.
Expensive and initially pays very little, but a Pilot might meet some of your criteria. Also, real estate or some of the other broker positions might be good.
If I were you I would consider trying to find something you love to do for 40hours rather than finding something you don't like, and working less than 40. I know this is easier than it sounds, because you may not know what you like until you start actually doing it. Hope this makes sense and helps out. IMHO, even 15 hours a week is too many hours to spend doing something you hate.
