Ego is not the same as your art. What your ego needs from your art is different from what the world needs from your art. What your ego needs from your art is even different than what your art needs from you. Your art – your creative work – is the process. The end result is not different from or separate from the process.
But the ego, with best of intentions, says the end result is the representation of the process so it has to be perfect. The ego needs your art to be perfect. But you just need to do your art, and to make mistakes. This contradiction is the road to madness.
Tell your ego, your expectations, the whole ball of what your art “needs to look like” to go do itself with a crowbar. Then just start doing the work, even it looks and smells like a pile of dog poo. That is the path to growth and being a working artist.
