In human affairs of danger and delicacy successful conclusion is sharply limited by hurry. So often, men trip by being in a rush. If one were properly to perform a difficult and subtle act, he should first inspect the end to be achieved and then, once he had accepted the end as desirable, he should forget it completely and concentrate solely on the means. By this method he wold not be moved to false action by anxiety or fear. Very few people learn this.
— John Steinbeck, East of Eden
