Unless you like starving and living in a hole in the ground, you can use your artistic talent to make money! Of, course making money from you art is looked down upon by real artists but you can do it and become famous.
That is what Howard Terpning, artist and movie poster illustrator did and during his long commercial art career he illustrated over eighty movie posters, creating artwork for some of the most famous movies ever filmed. In need some inspiration? Then why not paint/illustrate some aspect of a book you are reading or a TV/radio programme you have seen.
