You may find it easier to compile several checklists (covering personal, study, and workplace, for example). Try different approaches and use the best for your own situation.
Mark the importance of the task next to it, with a priority from A (very important) to F (unimportant). Redraft the list into this order of importance. Then carry out the jobs at the top of the list first. These are the most important, most beneficial tasks to complete. You can also use software-based approaches to manage your checklist. You can often access these from anywhere, and they can often be synced with your Smartphone or PDA.
Write down all of the tasks that you need to complete on the checklist. If they’re large tasks, break out the first action step, and write this down with the larger task. (Ideally, tasks or action steps should take no longer than 1-2 hours to complete.)
Do you often feel overwhelmed by the amount of work you have to do, or do you find yourself missing deadlines? Or do you sometimes just forget to do something important, so that people have to chase you to get work done? All of these are symptoms of not keeping a proper "To-Do List."
