Morning sleep removes a man from the world.
Nowadays many young people go astray, into drugs and other self destructive behavior. Even if they come to their senses as adults, these years of youth, when their highest capacity to learn is available to them, are squandered and never regained. Children mimic adults' behavior. An adult who has a graduate degree, functions effectively in a large corporation, may be thought of as mature. But if that adult lights a cigarette, or on a more broad level pollutes the air or televises indecent or violent programming as part of his corporation's lust for money, sacrifices decency and morality and is anything but mature.
