Getting Things Done by David Allen is a highly popular foundation to create an ideal time management for yourself. If you want to learn more about all the aspects about time management, I would recommend to enrol to my time management methods master course. This course here is part four out of five. You can either enrol to selected course parts one by one or you decide to directly enrol to the full master course.
