You are right in demanding that an artist approach his work consciously, but you are confusing two concepts: the solution of a problem and the correct formulation of a problem. Only the second is required of the artist.
Without ambition one starts nothing. Without work one finishes nothing. The prize will not be sent to you. You have to win it. The man who knows how will always have a job. The man who also knows why will always be his boss. As to methods there may be a million and then some, but principles are few. The man who grasps principles can successfully select his own methods. The man who tries methods, ignoring principles, is sure to have trouble.
Work and thou canst escape the reward; whether the work be fine or course, planting corn or writing epics, so only it be honest work, done to thine own approbation, it shall earn a reward to the senses as well as to the thought.
