I'm currently a junior majoring in business. I've realized I don't want to do the 9-5 thing my whole life. Is there any way I can retire early without ever having to enter the corporate life.
No.
I'm interested more in healthcare than business. I started off as a nursing major but that was too much crap to deal with. My college didn't have too many options other than that besides teaching, engineering, and the sciences (chem and bio).
So I'm hearing that you're attending this college because it means you can live at home /be frugal.
But the college doesn't offer a major that really appeals to you.
That makes no sense. What are you going to have when you're done?
What you really need to do is decide what you want to do as a career -- and then find out where you can get the training for that career.
Next, you walked away from nursing because it was "too much crap to deal with". I know exactly what you're talking about: My daughter is a nursing major, and she had to jump through quite a few hoops to get into the nursing program -- then more hoops to prepare herself for clincials. Buy the school-colors scrubs with the school logo from this specific store, these shoes from that other place, TB test, drug test, proof of vaccinations, criminal background check so she'd have hospital clearance (and, yeah, every one of those medical tests and the background test cost money), summer school, go in between classes to be "signed off" on various skills, arrive at the hospital 6:30 in the morning -- and the hospital's an hour from the university, stay after 'til the nursing advisor has approved your daily work. Oh, yes. I hear her talking about the "too much crap"; however, this is the path to becoming an RN.
I did similar things when I was a student teacher.
My husband did similar things when he was an engineering student /intern.
Trying to prepare for a professional career without "too much crap" is the very definition of being penny-wise and pound foolish. It's a matter of proving yourself. Once you're in the job, maintaining all those credentials isn't so much work, but you have to reach that point first. What I'm hearing is that you're searching for shortcuts. That won't work.
