Sometimes, not even problem-solving will help you find resolution when writing or critiquing. Thinking is hard. Not thinking is even harder. When focused on your task, letting go can be challenging. The fear of never finishing what you started is a real concern and can drive you wackadoodle.
Not thinking isn't really a lack of thought, it's more of a diversion or a way of stimulating other parts of your brain.
Trust your intention, commit to the completion of your work and step away from the page. Let the resolution rise from your creative unconscious to your conscious mind. You may surprise yourself.
