Not being at a 121 doesn't make you any less of a pilot.
Arguably, the best pilots I know never set foot in a 121 cockpit, or only did so much later in their career. If anything, straight to 121 out of CFIing probably reduces your skills and capabilities. You're probably a better airline pilot than I would have ever been if you go that route and I'm not saying they're unsafe, but... I don't know, I think you miss out on something when you don't have to do something in the airplane where you have to face death here and there. Like, having to make decisions on your own unsupported by dispatch or another set of eyes to check your work until after everything is said and done is probably (maybe) a good thing for us. And I don't just mean pilots. The best guys I ever met in the airplane had really circuitous routes to success and had done some weird things working in some objectively dangerous situations. They also LOVED flying - no scratch that - they were IN LOVE with flying and literally couldn't see themselves doing anything else, so they "made it work" often times when perhaps that shouldn't have.
And
@Maximilian_Jenius - to add to this, it's alright. Aviation eats her young, and it's totally OK to say, "wait a second, I'm going through this so I can drive around a piece of heavy sky machinery?! WTF?"
Looking back at my time "post-career" I really think there's a sort of resilience that gets built up when you're just going to do whatever it takes to learn and grow and "make it." You will put up with whatever sort of • you need to put up with (albeit usually temporarily) if it moves you towards your "goal" - whatever that is. If that goal is not defined, or something nebulous like "a good and comfortable life" it's going to be very hard because it's half a decade to get there at least. Knowing more about myself "now" - I don't think I would be willing to eat crap for 5-7 years to get where I eventually got to. Hell, I am literally contemplating going back for *more* school to do some engineering course ware and broaden my horizons and even now, at 37 I am thinking, "man, doing the aerospace engineering curriculum would be really fun and awesome... but I just got done with grad school and it was exhausting - do I really want to subject myself to that again for 2 years?" I cannot imagine having the energy or patience or motivation to start a flying career over again. Even if there was a magical pill where I could take it and I'd get my vision back to normal but the catch was "you have to start from scratch on your flying career certificate wise" I do not know that I would be willing to do it. I miss it literally every day - but... the ass pain associated with the job is high and someone tapping out is totally understandable.
I remember when we talked about going to the bush, going to Grant, or whatever, Max. That's kind of a young man's game - I mean - the bush, the west Alaska or the arctic, the type of flying, the work, the stress. In my mind it was ALL very fun - but not every person is cut out for that, and that's ok! Conversely, I have two friends now who have made it into the right seat of the 747 at ACMI du Jour and have decided, "wow, I really don't like this - the money is better, but I'm not fulfilled." Two friends who have said, "the brass ring ain't for me." One of them went back to flying 1900s up here, then pivoted into training and management. He's doing extremely well for himself and home every night (I should call him!). The other just said the hell with it and took a job doing King Air Medevac and left it all behind at least for now. Some people think they are crazy - so be it - but those guys know what they want out of life and are getting exactly that.
Even me, I went down to the lower 48 to build turbine time. I moved like 5 times in like 3 years lol. It was terrible. I lost a relationship over it but also I ended up meeting my wife on this circuitous ass route so it wasn't all bad, but I won't say that flying cargo and prostituting myself out for turbine time was a particularly pleasant experience. I remember the "house meeting" when the police searched the cheap ass flop house I lived in in FSD for $200/mo (
@jhugz remembers this time in my life). I also had a LOT of fun, but I was 23 with 4000tt and a penchant for drinking heavily on the one day off I got a week. I'm not saying it was all bad, but I also wouldn't do it again, and I sure as hell wouldn't do it now and I certainly wouldn't do it when I was your age (that's not a slight, it's just I no longer have the tolerance for those kinds of shenanigans and I can't imagine dealing with it in a decade).
Anyway, I just woke up this morning to go to work, and I was kind of thinking about this post a little bit - you should know it's ok to tap out of flying. 15 years ago I might have even talked • or rolled my eyes "oh, boohoo, I am making it, how hard can it be?!" but that Pat was kind of dick at times and he was 22. Currently, this version of Pat today has seen some • and is (just in general) very tired. I just want to reiterate that it's totally ok - even admirable that you're doing the stuff you want to do instead of looking for this external sort of validation that flying gives you, and you not wanting to subject yourself to the "suck" is probably a smart move. I see a lot of chronically unhappy people in this world that are doing a lot of stuff because they either A) have no idea what they want so they're just trying to do something that the people that they admire want, or B) get what they want but are so unhappy in their life that they lack the ability to enjoy precisely the thing they always thought that they wanted, or C) never "make it" so they are always kicking themselves for not going for it.
You're none of thse - you decided to basically abandon that and focus on yourself and the stuff *you* want to do... that's pretty cool. I hope school is hard in the most fulfilling way and you're successful in all the ways you didn't know you wanted to be.
