I know what I chose and I'm not happy with my decision but I don't regret either, I dropped out of high school[footnote]Not to work, mostly because I was ridiculously emotionally unstable and had a nervous breakdown in the middle of class which left me too embarrassed to ever go back, which is a thing my family genuinely thought was hilarious, yet I've still wasted my life for them, relationships are complicated.[/footnote] and I worked hard, I supported my family and kept them from starving, my brothers wouldn't have been able to study if it wasn't for me, so no I don't regret it at all, I think it was a good noble choice to make, somebody has to make the sacrifice after all, but I'm most definitely not happy, I hate my job and the combination of that and the pressure of having to maintain a family of what is mostly people older than me made me really angry and frustrated and as a result we aren't really on speaking terms any-more even though I still send them money, it's pretty weird I absolutely hate them but I can't just leave them and the funny thing is that now I'm so bitter and tired that I just don't have the conviction to do anything.
It's nice to sacrifice something for someone but you gotta remember that in real life that doesn't mean they'll help you or even be nice to you, then again it's possible than I'm just a sucker, though I'm pretty sure I like being a martyr, I never even think twice about giving up something for someone else and I do like to brag about what an amazing human being I am.
In any case, there's no right answer, it's true that my life would have been better if I had studied because I'm a really fast learner, plus academically I was pretty smart and with the hindsight of knowing how I work and how highly most of my colleagues think of me it's pretty safe to say that I would have found success in whatever career I chose, I mean I'm hard-working, dedicated, smart an generally pretty nice, but I also have a ridiculously strong moral code and sense of duty and I probably would have been miserable thinking I didn't do what I felt was the thing I was morally obligated to do, in my case I don't think there's any possible scenario in which I'm happy but depending on what kind of person you are it might vary between choices, of course not everyone has to make that decision.
