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.
To-Do Lists can help you get, and stay, on top of important projects and piles of tasks or decisions. For instance, imagine you’re heading a team that’s working on a project. There are so many tasks to do, and so many people doing them, that staying on top of it all seems overwhelming.
Mastering procedural processes and repetitive tasks with checklists allows you to focus on the larger goals at hand. It’s the minutiae of the workday that can be easily forgotten at the detriment of other important projects.
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.
