Listen. Never be afraid to just make something.
Even if it’s a bad idea, even if it seems improbable, or amateurish, or overly complicated; even if it’s only half fleshed out and you don’t know how you’re going to finish, or it’s a medium you have never worked with before.
You never know where it’s going to lead until you try, and I think you’ll be pleasantly surprised at how often you’ll come out the other side with something you’re proud of. Even if you don’t, I promise you’ll learn something valuable for next time.
Eventually, somewhere along the line, you may discover a talent or a passion you never realized you had. Only by making things can you discover your identity as an artist.
