Earl Nightingale is a prophet of believing in yourself. This album is not about real-estate brokers. He occasionally mentions realtors as his audience, but his message applies to everyone in any job, in any economy, in any place, at any time. This is not outdated. His messages only become outdated when you expire at the end of life.
Just take a quick look at the track titles to get an idea of what you'll hear. If you can break away from your TV or radio for fifteen minutes a day to hear him out, he will change your life. The messages you will learn from Earl Nightingale are worth a hundred times cost the audiobook.
