This is a great piece of advice. I agree to the idea of writing only when inspired not to torture oneself and the story. Because the joy we put in doing something, even the mundane tasks like cooking, shines through and the product of the work is useful for people, helps life flourish somehow (although we do not see or, rather, have forgotten to see the connection). For me, moments of inspiration are almost always early morning or late in the night, when the critical, judging voice or, perhaps the will, is absent or weak. These are moments of altered states of consciousness when everything is experienced more directly, vividly and naively. And words are formed, almost without effort or against will, to express the flow of emotions and ideas.
You have referred to us having lost the gift of storytelling. Is that because we think too much? Have we entrusted life to the intellect? Does the will have a role to play here? Do we have to silence the intellect or the will to start telling and connecting to our life and to others?
