How do you know what you like until you have experienced it. Take foundation courses in drawing, 2-D design and 3-D design and expose yourself to museums, artist studios, and galleries.
Ask an artist how they knew what you wanted to do for a living. Perhaps, they will tell you they have another job to support themselves if they are fine artists. Perhaps they just love to create works of art to show and sell. You may find you want a career in fine art but also want to complete a degree in digital art to have a better chance of finding work.
The Bureau of Labor Statistics state that fine artists have a second job as a teacher or curator. The BLS also stated that artists held about 218,000 jobs in 2006. More than 6 out of 10 artists were self-employed. In contrast, artists held about 50,300 jobs in 2014. About half were self-employed.
