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.
Or, imagine you’re in a sales role and have a long list of people who you need to talk to. You write out a checklist of everyone you need to call and every client you need to see, and start prioritizing.
Mark the importance of the task next to it, with a priority from A (very important) to F (unimportant). Redraft the list into this order of importance. Then carry out the jobs at the top of the list first. These are the most important, most beneficial tasks to complete. You can also use software-based approaches to manage your checklist. You can often access these from anywhere, and they can often be synced with your Smartphone or PDA.
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.
