A 19 year old pilot on the cusp of getting his instrument rating last night asked me what my "dream aircraft" would be. I think he was a little hurt when I said "The one that will pay me the most money to keep me home the most time. I'd fly a 172 if I could get a better paycheck out of it and be home more often." He seemed a little upset when I told him flying was a job and that just because it goes fast, doesn't mean you'll like it.
Moral of the story - Fly whatever is going to make you happy, pay the bills, and get you home.
