Where do you go from here Brian? Different plane?
Not right away. There are several factors involved.
Flying-wise, I'm going to focus my free time on studying for my instrument rating, rather than looking for every waking good-weather moment each week I could potentially go flying.
Money-wise, the 150 has been mine free-and-clear for a few years now, so 100% of what I get for the plane will go in the bank and earn interest for a bigger plane down the road.
I'd eventually like to get my commercial rating, and do something with it for a living. Maybe get my CFI? Start some sort of local charter? Not sure. No matter what I decide to do, something like that likely wouldn't happen for several years.
