Jobs and Careers

So I've been looking for a job for the longest time, submitting tons of applications all over the place and still can not find anything. Now I'm trying to figure out a career for myself and am falling short there as well. I know I want to major in Photography, but where will that get me? I don't want to live paycheck to paycheck trying to figure out how I am going to be able to afford everything. I would like to stay at the school I originally started at, Point Park, because, although I was there for only one semester, I loved it. But I am a little limited there as to what I can go into unfortunately. I have recently been reconsidering my original plans as either forensic science or psychology. Unfortunately Psychology can be the same way as Photography, sure some people can go out and find great jobs and make great salaries but others can be trying to figure how to survive on what they make.
So yet again I'm back to not knowing what I want in life. If I went with what I love to do it would be Cooking or Photography and unfortunately those can be kind of sketchy careers to have just because you could end up working and making just above minimum wage.
As for the job thing, I have no clue what is up with that. I read a newspaper article not that long ago that basically said teens are going to have an even tougher time finding jobs this year due to a series of different things. What sucks is I have bills to pay and no way to pay them right now. I was thinking for a while, what if I do an at home photography business where I go and take pictures at family events and such for cash, but I know. I wouldn't even know where to begin to advertise myself for something like that. Sure I could put ads in local papers, but I am an amateur photographer and although I know I am good and can take some really great pictures, I just don't know that people would actually go for something like that. So I have no clue but I need to find something fast! I understand I barely have any experience but I've got an excellent work ethic and I'm a fast learner and I just wish employers didn't go so much by previous experience and interviews because someone could have an excellent looking work experience and be the perfect interview but be a horrible employee who never shows up and fulls around on the job. You never know until you hire someone.
Right now, I'm just trying to figure out my life and what I want to do with it. Unfortunately, it's a lot longer thought process then it ever was when I was in high school.
