You can be an artist and not sell your art. You may find as you go through the steps to become an artist for profit that you don't really like being a business. That happens sometimes. It's totally ok to try it and find out you do not enjoy the business part of being an artist, that you just like the creating part. There is no shame in learning that you do not enjoy the game. While I loved working on our journaling books, during that whole process I learned that I hate being on tv. I learned that there are certain parts of the job I love and others I love way less. I am an observer and the shyest one of the Goldberg kids. I love making art. I love visual storytelling. I love marketing. I love inspiring people. I do not like being in front of a crowd. Once I realized that, I was able to really focus on the parts of the art career that I feel most comfortable with. Sometimes the dream you chase ends up feeling much different than when it was only a dream. If you are just starting out, really pay attention to what makes you feel good and what parts are making you feel icky.
Making art not for profit in NO WAY makes you less of an artist. Don't let a lack of sales or a lack of enjoying the selling process define you as an artist. You do not have to sell art to be an artist.
