Same thing I do now, but instead of full-time work / part-time student, I'd flip it to part-time work and full-time student.
I'm hanging on to the bottom step of the medical ladder - this field is fascinating as fuck, and even as just a tech I get a lot of satisfaction in my role (albeit minor relative to doctors or nurses) in helping others recover from whatever sickness/injury they present with.
Without the financial barriers and current need to work till exhaustion to afford rent, I'd be highly interested in going all the way to physician, but at the rate I'm able to actually afford the time and money to take classes, I'll be pushing 40 when I'm able to clear the hurdle from tech to nurse; and it already hurts to move half of my fucking joints, so once this nursing shit is finished, I don't see myself climbing any more ladders, literal or otherwise... at that point it'll just be the counting the days till retirement or planning out the most pleasurable way to commit suicide.
