There are lots of ways to pursue your passion for art. You could treat your art as hobby, and make money doing something else. On the opposite end, you could investigate careers that would allow you to pursue your art and make a living.
The good news is that there are lots a careers that involve art skills. I've answered similar questions on Career Village, so you might look up those responses. But you need to start investigating careers. I'll give you some ideas, but I strongly suggest you also talk to your art teachers or other students or academic advisors. Here are a few areas you could check out on the internet to get started:
Graphic designers ( design things like books, magazines, business logos), industrial/technical designers ( design things like cellphones, furniture, cars) , fashion designers (design clothing), interior designers (design the inside of houses and businesses), art teachers (all levels) , museum careers (curators, conservators), jewelry designers, fine art painters, photographers, sculptors, illustrators, website designers, and theatre arts. There are many more.
Whatever art field you choose, be ready to: work hard, be humble, be flexible, keep on improving your skills, take advice from more experienced artists, and be patient, finding an art job takes time. While you are still a student, check out internships to gain some inside experience.
I used my passion for art as an art teacher. I loved my job, and I got to talk about art 5 days a week for 8 hours a day to young artists. To find out more information about teaching art, google the the National Art Association website.
Best wishes. I hope this helps.
