What are you working on in your studio right now?
I never really know when things are finished. I will pick a spot at which I feel like if I go further I could squash the breath right out of the painting, and then I will set it aside. It is usually a few days later that I will decide if it would benefit from me working longer on it. I try to not get too excited about anything right away because there is a split second that occurs when you return to your space on a following day in which you can see things objectively. In that objective moment things can look surprisingly good, or terrible. Sometimes you can see that something is finished when a few days prior you were sure that it wasn't.
