“After thirty years of intensive research, we can now answer many of the questions posed earlier. The recycle rate of a human being is around sixteen hours. After sixteen hours of being awake, the brain begins to fail. Humans need more than seven hours of sleep each night to maintain cognitive performance. After ten days of just seven hours of sleep, the brain is as dysfunctional as it would be after going without sleep for twenty-four hours. Three full nights of recovery sleep (i.e., more nights than a weekend) are insufficient to restore performance back to normal levels after a week of short sleeping. Finally, the human mind cannot accurately sense how sleep-deprived it is when sleep-deprived.”

“Do not love half lovers
Do not entertain half friends
Do not indulge in works of the half talented
Do not live half a life
and do not die a half death
If you choose silence, then be silent
When you speak, do so until you are finished
Do not silence yourself to say something
And do not speak to be silent
If you accept, then express it bluntly
Do not mask it
If you refuse then be clear about it
for an ambiguous refusal is but a weak acceptance
Do not accept half a solution
Do not believe half truths
Do not dream half a dream
Do not fantasize about half hopes
Half a drink will not quench your thirst
Half a meal will not satiate your hunger
Half the way will get you no where
Half an idea will bear you no results
Your other half is not the one you love
It is you in another time yet in the same space
It is you when you are not
Half a life is a life you didn't live,
A word you have not said
A smile you postponed
A love you have not had
A friendship you did not know
To reach and not arrive
Work and not work
Attend only to be absent
What makes you a stranger to them closest to you
and they strangers to you
The half is a mere moment of inability
but you are able for you are not half a being
You are a whole that exists to live a life
not half a life”
― Gibran Khalil Gibran

“Practice does not make perfect. It is practice, followed by a night of sleep, that leads to perfection.”
