Personal Fitness as a career
For college students the entire point of this whole experience is to build up skills for things you will do for work later in life. Most of our experiences are meat to build up skills that you will use in your careers or in pursuing the goals you have for your life in the future. Unless you are like me and are in a program like education where you are required to teach the whole way through college to get better at it, you don't necessarily get to apply your skills much till it's all said and done.
Concurrently there are experiences that you can have in college that are meant to be used right away and for some these experiences might just overtake the dream you had when choosing your major. These sorts of things usually crop up from your hobbies like those people who graduate as engineers who go o to become rock stars or something. They can also come from the myriad jobs that are available to people attending college who need the work. I have a friend who got his Personal Fitness Trainer Certification while getting his English degree. If that kind of thing interests you then now is the time to do it. You don't want to wait until you have a career going and bills to pay to finally Learn about Personal Training as a job, or any other alternative to your degree that might exist.
The point is is that there are may things that we ca do for a living i this world that don't have to fall under that ominous umbrella of the major we've chosen. I mean as of now I am interested in doing things like teaching outdoor school and building guitars ad my major is education. I mean the big title I will have at the end of college doesn't have to mean that all my other interests are evaporated from my future. That's just the one that I personally saw as the one that would be the easiest to get a job at that would pay for me to pursue the other things as well. Maybe I'm just a wandering sort of person, but maybe you are too if this resonates with you as well.
