I agree 100% with
Vex. Glad you posted what I was going to say.
Candeka also offered good advice.
It might help if I explain my story:
Went into college not knowing what I wanted to study. I was pushed into choosing a major after 1 semester (I should have waited, in retrospect). I chose something I loved...Theatre. Specifically, technical theatre. Backstage stuff like costumes and stage management and lighting...mostly stage management. I worked my booty off in college, filling my resume with shows. By the time my Junior year rolled around I was the best Stage Manager in the department, hands down. Went to job conferences for Summer internships. I loved it...for those 4 years. Then I was in a miserable internship where I wasn't happy with the work or most of the staff. And I realized that while theatre is fun...it doesn't offer the job stability or decent pay that I needed, and it was a very high stress/thankless job.
So now I'm in school again, which will give me a good degree, but it's costing me about $50,000...probably more. When I graduate, I'll have a career that will give me opportunities all over the US (important to me), flexibility on hours/ability to work part or full time (important to me), and a great salary (important to me). Will it be a job I love? Most days, but that wasn't at the top of my list this time around (in the top 10, but not the absolute top...if that makes sense).
So while it's important you do something you love, it's also important to be realistic about money (hey, bills need to be paid) and your future. I'm very fortunate that I had scholarships the first time around in school, so I don't have student loans from before.
Not trying to knock down your hopes and dreams. I'd look into what options you have, talk with your school counselors or any personal trainers you have access to. See what they have to say/what degrees they have/if they have any tips or suggestions.
