Superhuman By habit - Tynan
Good sleep feels like a luxury and a superpower at the same time.
Sleeping as long as you want to and waking up without an alarm clock
smacks of being on vacation, but being alert and working at your peak
when others are dragging and relying on coffee makes you feel
invincible.
The goal with good sleep is to get as much sleep as your body wants,
probably around 8 hours on average, and to wake up without an alarm
clock.
A long term view is critical when attacking the sleep
habit. In any given week, you can sacrifice your sleep for more time
spent working, and possibly even more high quality output. But over
the long term, you'll find that the quantity of quality output you are
able to produce will be directly correlated to how closely you are
able to follow your body's natural sleep patterns.
