"So many of the highly successful and enlightened people I know share a common habit: they listen to audiocassettes in their cars. In doing so, they transform their driving time into learning time and make their automobiles moving universities. Turning your car into a "college on wheels" will be one of the best investments you will ever make. Rather than arriving at work tired, frustrated and dispirited, listening to educational audio-cassettes will make your commute fun and keep you inspired, focused and alert to the endless opportunities around you."
