Most of our mental development and study discipline comes through formal education. But as soon as we leave the external discipline of school, many of us let our minds atrophy. We don’t do any more serious reading, we don’t explore new subjects in any real depth outside our action fields, we don’t think analytically, we don’t write — at least not critically or in a way that tests our ability to express ourselves in distilled, clear, and concise language. Instead we spend our time watching TV.
