Quote by Bill Watterson
Shutting off the thought process is not rejuvenating the mind is like a car battery - it recharges by running.
Summary
This quote suggests that simply shutting down and avoiding the act of thinking does not refresh or revitalize the mind. Instead, the mind recharges and rejuvenates itself in a manner similar to a car battery, by actively engaging in mental processes like thinking. Just as a car battery gains power while running, the mind gains energy and renewal through the process of contemplation and intellectual stimulation. In other words, turning off the mind completely can impede its ability to replenish and grow.
