And I'm not kidding - it's free.
Joe Polish and Dean Jackson have been offering a free podcast called "I Love Marketing" on iTunes now for over a year.
If you travel to work, listen to a podcast a day.

There's no charge and there's rarely a pitch.
Solid timeless teachings.
Now go make some money. The material is classic and awesome.
