Why do you need a “career” as such? I get the student loans are a pain in the ass, but maybe do the trip thing, get a job as a bartender or something. Don’t be afraid to make change because you feel obliged to stick to a certain path.
Yep, maybe business school was a waste, might be hard to accept, but once you do and focus on where you want to go, not what’s holding you back, there might some indication of where that is. Even if you have to stick it out for another 6 months – a year to save some money – you have a goal in mind, something actionable, rather than the constant wondering you might feel better.
