Ah, are we ever fully satisfied with what we create or how much we know? I'd like to think the nature of the artist is to explore and challenge him or herself, so my guess is that no, we are bound to be always trying new things. I'm like you, I enjoy creativity in all forms. I actually have to restrain myself from trying new art mediums, since I started in my 40s I try to stay focused on painting, but it's not easy. The struggle is real, lol.
