Estimate how long each item on your To-Do list or Action Program should take to complete, and allocate a set amount of time to each one.
Set a timer to alert you to when you should move on to your next timebox.
If you don’t finish your task within the allocated time, you might be tempted to continue until you reach your goal. However, make sure that you analyze what you’ve accomplished and review your progress at the end of each timebox.
Ask yourself the following: Did you complete your work? If not, why not? How will you schedule your tasks differently next time?
