@Maximillian_Jenius - I get where you're coming from. You were still training when I joined this site, fresh out of a divorce, trying to figure out if ATP was the right place for me to go. Didn't happen.
From where I stand, I don't see why you couldn't do both; have a private practice and work as a pilot. One of the huge benefits of airline flying is knowing your schedule a month or so in advance, and having some degree of control in how much you fly. This definitely allows you to establish schedules with patients.
And, I don't know how feasible it is, but I could see you picking up work with other pilots; how many pilot-psychologists are there? How much good could you do counseling other pilots, who have a particularly unique set of issues to confront?
Or maybe that's not a good idea. The opportunistic part of me sees an under-served market, and potentially allows you to do both jobs, at varying levels of involvement.
With the week I had this week, yeah, I totally see the attraction of plunking down a chunk of borrowed change to finish out my ratings, even to haul ass down to ATP's RIC location or my local giant FBO and start grinding out hours to facilitate leaving this often cushy-yet-infuriating-job I do.
But here's the thing - and there's no getting around this. If I haven't learned anything else, I have learned to be honest with myself. And being honest with myself means that if I got into an airline gig, it would be fun for a while, but, as
@jtrain609 very bluntly put it some years ago, eventually it's just a job. And I suspect - I don't know, but I suspect - that I'd eventually not enjoy it anymore. Which why hobby flying/part-time flying is still right for me, while I ply my trade and take the corporate money that allows me to live comfortably and pontificate on the internet at my leisure.
So - know thyself, right? If you want to do both, perhaps you can, and perhaps THAT is what could keep those feelings of regret out of the equation.
@ATN_Pilot 's deeper advice - whether he intended it or not - is that pursuing your current track gives you OPTIONS. And OPTIONS, really, are what you want.
