Across the broad spectrum of human endeavor, one major factor that separates the successful from the unsuccessful is the ability to hone and hold their attention in order to attend to a task, develop a skill, and/or achieve a goal. Whether the effort is akin to an arrow or a plow, great attention must be paid to ensure ones direction is accurate and effort effective. Indeed; no great achievement has occurred without focused, diligent attention to a purpose, cause or goal.
