What do you do to turn off? If meditation primes the brain in the morning, then chilling out deflates the brain at night.
Some people watch movies. Some people social network. Some dual screen. Others escape with a book. And some people just pass out at 9pm. You probably do all three during the week, if not in one sitting.
The brain requires rest, just as the body does from exercise. Overexertion can hurt you more than it helps. Once you put in the work, the neurons need time to connect ideas and wash away the crap. Literally, the brain works like a dishwasher.
Maximizing productivity relies just as much as you put in and equally how much you zone out. You don’t always have to be on.
