I would never change it. Like Blendderpilot said, flying privately is so restrictive in what you can do and what you can fly. There is only so much of flying round the place with your friends that you could take, it would become tedious and boring after a while.
Flying as a profession allows you to fly all sorts of aircraft, doing all sorts of missions, in all sorts of places, what a pleasure. I love coming to work, its fun, exciting, I get to fly awesome machines doing great and challenging work and I get paid for it. What more can you want?
