Should I worry about my future job/career even though I'm only 15 years old?

no you dont need to worry about it, i would just stick to what your good at and what you like. im 20, doing a business degree, im finishing it next year and even though i love it i am going to do a medical degree! pretty crazy change but i am still young enough to do that! plus my business degree will come in handy in some way, im not sure how!! but experience is everything. you've got plenty of time to think about it.

Depends on what you want to do. But I would NEVER, EVER let it stress me out at 15 years old enjoy life. When I say it depends on what you want to do. What I mean is if you are interested in the entertainment industry. Modeling, Acting etc... Starting early is the best thing you can do. If you go to into Corporate America no need to start a career now.

Best Wishes!!
