Recently, The Art of Manliness provided an historical look at checklists, along with a detailed primer in deciding which lists will work for you, culled from the excellent, The Checklist Manifesto. You can implement the same routine in your daily work to help give you a greater shot at success.
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.
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.
What you put on your checklist and how you use it will depend on your situation. For instance, if you’re in a sales-type role, a good way to motivate yourself is to keep your list relatively short, and aim to complete it every day.
