I don't know about other artists but for me, putting my art out here was a slow process. I always find it difficult to show my creations, but at one point, when I saw the paintings I'd done over the years gathering dust in the corner (folder), I felt guilty, like I was neglecting my children. So I set them free. And when people expressed desire for prints, I started selling prints. I didn't have a specific plan or goal in mind.
My advice would be start today, be consistent, have patient, do research about the market, the audience. Have faith in your creations, keep making what brings you joy and your creations will, in turn, bring joy to others. When it comes to the commercial aspect, be reasonable and respectful, of yourself, your art, and your audience.
