It's hard when you're expected to choose a career that you are supposed to work in for many years to come before you're even 20. I went through something similar that you're going through now- maybe it will help? I started college like you probably around age 18 and sort of just "fell into" mathematics and business/market research even though math bores me to death and I am not cut out for corporate america at all. To make a long story short, both of my parents are workaholics and highly successful business people, so I was somewhat persuaded to get into this type of work and I had my master's degree in statistics by the time I was 23. Thankfully I had scholarship
/assistantships and my student loans aren't too bad, but I am stuck paying quite a bit to say the least.
I worked for 3 years almost exactly in the corporate world as a statistician working a desk job for a company whose ethics I despised, making rich people richer, and doing the same boring work day in and out. Even at age 25 I couldn't get the courage up to dissapoint my family and leave the business world. Finally, this year I did find that courage and now I am a new nursing student, pursuing something that I have wanted to pursue for years now (being on my feet, helping others, etc.)
I work as a CNA now to help pay for school and can't wait to become an RN. You should have seen the faces of my "professional," educated co-workers when they found out I was leaving my comfy benefits and desk job to clean poop and give people baths all day. My parents were a bit stunned too at the CNA thing, but I am honestly loving every day of it. I love caring for people who desperately need it, being on my feet all day, moving around, and most of all, talking to lots of different people every day and making a small impact in their lives. So I don't mind the poop.
My point is this: Do what makes you happy, not what you think will make OTHERS happy. One person's trash is another person's treasure. Maybe the business world will make you happy. Or something else entirely. My job now scares most of my old friends. Do I care? NO! I love it. It's their trash but it's my treasure. I only wish I'd had the courage to pursue a better-suited career BEFORE I ended up with all those student loans and a master's degree in an unrelated field. But, it's never too late to start over.
My suggestion to you is to do some serious searching and find out what you like. Maybe volunteer for some different types of jobs or "trail" someone at work who works in a field that you're interested in. Ask them lots of questions. Go on an informational interview. No job is ever going to be perfect, but you can find out the pros and cons ahead of time before you continue spending a lot of money that you will never see again. If you have questions about the business world, I will be happy to answer. My sister-in-law is a psychologist, so I also know a bit about that too-- fyi, she had to go to about 10 or 11 years of post-high-school education to become fully licensed and to get the ph.d, etc and all that and she only makes slightly more than what I do now as a CNA. It's hard- in a lot of careers, you have to start out at the bottom and work your way up. So it's helpful to know all the pros and cons before going into something.
Okay off my soapbox, I hope this helped a little. It's never too late to make YOURSELF happy. Remember, YOU are going to be the one having to clock in and out of a job you either love or hate every day, NOT your mom or your uncle or your auntie. And trust me, it's a lot better waking up every morning and going to a job you like rather than one you dread.
