In this blog post I am going to demonstrate a simple workbook where you can create or delete projects and add "next" actions to each project. You can also mark actions completed.
"The Getting Things Done method rests on the idea that a person needs to move tasks out of the mind by recording them externally, so the mind is free from the job of remembering the tasks that need to be completed. One can concentrate on performing the tasks, instead of remembering." Source: Wikipedia
