One factor which all successful people have in common is effective time-management. You may prefer to call it structure, setting yourself to the task, or a game-plan. Whichever word or term works for you is fine. As long as you take it seriously, and put it into practice, you are creating one of the basic principles of productivity.
It might be a good idea to think about this, and why this factor is so essential to success. Perhaps you can begin by thinking of the opposite– ways which do not work. Even if you have one very small task to complete, if you do not manage your time appropriately it may get done too late, or not at all.
