With this guide, I'd estimate I've saved about 2 hours per day!
2 hours per day x 5 days per week x 50 weeks = 500 hours
730 hours = 20 days saved
This rough math tells me I probably gain an additional 20 days to my work output each year because of this to-do list system.
Now it's your turn to save two hours a day, or 20 days a year!
