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."
To-Do Lists are particularly useful when you have a small number of tasks that you need to complete. However, they can become cumbersome when you have too many items on them, or when you need to progress multiple projects. At this stage, it’s worth starting to use Action Programs, which are designed to manage more complex situations reliably.
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.
To use your checklist, simply work your way through it in order, dealing with the A priority tasks first, then the Bs, then the Cs, and so on. As you complete tasks, tick them off or strike them through.
