"Gain disguised as loss” is a potent artist’s tool. To acquire it, simply, brutally, ask: “How can this loss serve me? Where does it point my work?”
The answers will surprise and liberate you. The trick is to metabolize pain as energy. The key to doing that is to know, to trust, and to act as if a silver lining exists if you are only willing to look at the work differently or to walk through a different door, one that you may have balked at.
