After much research and using myself as a guinea pig, I'm able to share my findings on how to sleep less, much less.
What do you need:
To realize how much time of your life you spend sleeping
To realize what can you do with 3 more hours a day
To realize that what you need is more energy, not more sleep time
Step 1: To optimize sleeping time
You need to have the most natural light you can get.
You can start by leting your sunglasses at home, opening the windows as soon as you wake up and if you spend to much time indors, buy a daylight lamp, the ones that people with Seasonal Affective Dissorder use.
