Mostly obligations I've got that are tying me down. I'm a year or two out from finishing my degree, so if I bail now I'll be wasting a lot of time and money I've already sunk into it.
Furthermore, my family do not understand this drive for adventure at all, and I know for a fact that even weekend trips to other cities scare the everloving hell out of them- they freaked when they found out I spent a weekend traveling with strangers to a festival. I live in a different city from them, so I could probably travel for a month, maybe two before they'd notice- but if they ever found out I'd end up estranged, and they've always been good to me- plus on a more selfish note, I'm still not entirely financially self reliant yet, though I'm working on it.
So I gotta hold on and keep grinding that 9-5 for a year or two longer. Gotta establish myself as financially independent, gotta finish that degree, and gotta figure out how to compartmentalize my life to keep my family from ever learning about it- because if I have to choose between my family or my dreams, there's only one right decision, and it would tie me down for good.
I can't and won't just burn all my bridges and never look back, because I know I won't want to ride forever, and I want to lay the foundations for a quiet life when I someday settle down- so that means I gotta work now, and hope that effort pays off someday.
Until then, I guess I'll keep dreaming.
