What if you had 48 hours in a day?
You could work more, sleep more and do more tasks in a day. You would be wondering that 48 hours day is not possible. But by increasing your productivity twice, you can do 48-hours tasks in 24 hours day.
Everyone knows someone who works full-time, runs some side-business and still somehow finds time to play his favourite game, visit friends, go for shopping or even watch the latest movie!
How does anyone have time for work, family, friends and even hobbies?
These super-productive people have same number of hours in a day as the rest of us, but somehow they get more things done.
