For me? I have no idea. After getting my license at 17, running out of money, then going into the tech industry to "finish up", I'm kinda enjoying starting over in aviation. It's not like I've managed to save any money this whole time, but I have managed to have a whole lot of fun. In a way, it's all gravy. Though to be honest, I can't do what I'm doing now forever—I've never been content to settle, and I've always wanted to explore. And frankly, flying single piston-engined wheelplanes at max gross weight over unlandable, mountainous terrain in 500' ceilings with a mile of visibility is bound to catch up to one eventually*.
I don't have an "end game"—for me, everything I do is more or less what I want to do. I don't know what I want to do next.
Perhaps surprisingly, I'm considering the (er, bigger) regionals. Or float flying. Or something in a twin. I've always loved multiengine airplanes, especially if they have radial engines. ^.^
So yeah, I dunno. Can't imagine I'll ever fly for a major—I spent a bit of time on the online degree thing, and couldn't deal with paying money for that level of inanity, or having condescending English teachers with terrible grammar telling me that I can't begin a sentence with a conjunction—but I wouldn't mind flying for a "proper" airline at some point. Especially in a E120 or similar.
For a while.
Have fun, do what you like, explore new things.
It's all gravy. ^.^
