You have to go away from it to sleep. You can’t sleep in your office all the time. Anytime at all is no good for you, because the cells absorb all this environment, the hectic-ness or the anxiety or the work, or, whatever that you do, even without you knowing it, and the brain also, and then it will be overloaded. The body is like a car; you can’t drive forever; need to rest, no? No matter how good the driver is, the car needs to rest. The same with my body, also. Even if I’m a good driver, my body makes trouble.
