magine you are driving a car across the country. At some point, your car is going to run out of gas. Usually, we fill our gas tanks before it gets to empty. But every once in a while, we push it out as long as we can. What do you do when your gas is empty? Do you keep driving? No, you cannot. Eventually, your car will stop moving, until you refuel it. Your mind is just like your car. It needs to be refueled constantly. If you push your mind too far, it too will stop functioning properly.
