The irony of time management is that many of us just can't find the time to manage our time. Habits and pressing duties keep us from setting priorities, breaking down tasks and getting organized.
The simplest step you can take is to plan for tomorrow. Make a written to-do list of the things you want to accomplish. Keep your goals realistic -- relate them to larger goals if you can. Assign particular time slots for when you plan to do a task. You might want to include some facet of time management on the list. In other words, set aside an hour or so to get organized.
Planning your day gives you two immediate payoffs. First, it can ease stress. Without a dozen things to juggle in your mind, you can get a good night sleep. Second, it helps you hit the ground running. You know what you need to do, and your first task is ready and waiting.
