" The feeling that we have endless time to complete our work has an insidious and debilitating effect on our minds. Our attention and thoughts become diffused. Our lack of intensity makes it hard for the brain to jolt into a higher gear. The connections do not occur. For this purpose you must always try to work with deadlines, whether real or manufactured. Faced with the slenderest amount of time to reach the end, the mind rises to the level you require. Ideas crowd upon one another. "
