Run through these checklists allocating priorities from A (very important, or very urgent) to F (unimportant, or not at all urgent). If too many tasks have a high priority, run through the list again and demote the less important ones. Once you have done this, rewrite the list in priority order.
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.
Task checklist have each step written in details which need to be followed in chronological order. While To-do checklist include a list of personal things that need to be done one after the other or simultaneously over a fixed time period.
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.)
