An average human being sleeps through one-third of their life. An average cat spends two-thirds of its life asleep. That should tell you just how important sleep really is for all living creatures out there. Because of that, evolution did not leave it to chance but developed certain principles that ensure a good night’s sleep most of the times.
We favour people who can only do one thing and do it well. We don’t encourage people to explore other avenues, instead pigeonholing them into what they can currently do instead of what they are and what they can be.
And I’m taking a stance here in saying that this is wrong, at least if our purpose is the thrive in this day and age.
