I define "grindin'" as just nonstop work! Nonstop work, nonstop progress. Can't sleep during that grind - I mean, you get a little bit of it, but if you're progressin' at every hour, every second, you are grindin'.
My mind is a chest of drawers. When I wish to deal with a subject, I shut all the drawers but the one in which the subject is to be found. When I am wearied, I shut all the drawers and go to sleep.
When I was going through menopause, I didn't sleep. I didn't sleep for two years and ended up blowing out my thyroid, and I became nonfunctional. It's difficult to remain fully present if I'm not getting enough sleep, so I work at getting enough.
We were not made by Nature to work, or even to play, from eight o'clock in the morning till midnight. We ought to break our days and our marches into two.
Now I know That twenty centuries of stony sleep Were vexed to nightmare by a rocking cradle, And what rough beast, its hour come round at last, Slouches towards Bethlehem to be born?
There is a saying in Tibetan that "at the door of the miserable rich man sleeps the contented beggar". The point of this saying is not that poverty is a virtue, but that happiness does not come with wealth, but from setting limits to one's desires, and living within those limits with satisfaction.
Thou fool, what is sleep but the image of death? Fate will give an eternal rest.
[Lat., Stulte, quid est somnus, gelidae nisi mortis imago?
Longa quiescendi tempora fata dabunt.]
On your eyelids crown the god of sleep,
Charming your blood with pleasing heaviness,
Making such difference 'twixt wake and sleep
As is the difference betwixt day and night
The hour before the heavenly-harness'd team
Begins his golden progress in the east.
Everybody should do in their lifetime, sometime, two things. One is to consider death...to observe skulls and skeletons and to wonder what it will be like to go to sleep and never wake up-never. That is a most gloomy thing for contemplation; it's like manure. Just as manure fertilizes the plants and so on, so the contemplation of death and the acceptance of death is very highly generative of creating life. You'll get wonderful things out of that.
