“ If we know that the inevitable setbacks and frustrations are phases of the natural cycle of creative processes, if we know that our obstacles can become our ornaments, we can persevere and bring our desires to fruition. Such perseverance can be a real test, but there are ways through, there are guideposts. And the struggle, which is guaranteed to take a lifetime, is worth it. It is a struggle that generates incredible pleasure and joy. Every attempt we make is imperfect; yet each one of those imperfect attempts is an occasion for a delight unlike anything else on Earth ”
