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.
If you’re after a particular kind of to do list then feel free to search the heading you’re after and skip ahead, but otherwise strap yourself in and feel free to grab one or more of the following templates to organize your important tasks. All of these checklist samples are freely available – just open them and then make a copy to have your very own template.
By keeping such a checklist, you make sure that your tasks are written down all in one place so you do not forget anything important. And by prioritizing tasks, you plan the order in which you’ll do them, so that you can tell what needs your immediate attention, and what you can leave until later.
But in you’re in an operational role, or if tasks are large or dependent on too many other people, then it may be better to focus on a longer-term checklist, and "chip away" at it day-by-day. Many people find it helpful to spend, say, 10 minutes at the end of the day, organizing tasks on their list for the next day.
