This American Life is such a great radio program and you can easily subscribe to and/or download the podcasts to your iPhone for free. Recently they aired one called "It's Not the Product it's the Person" and everyone should listen to it - or at least to the Prologue (Super Business Girl) and Act One (I Got 99 Problems and a Pitch is One of Them) - because the theme is on starting a business, and it's totally inspiring, and educational. You can also see a clip of Super Business Girl on YouTube:
