If you're serious about finding a product idea or taking your existing idea to the point of a successful launch, the MICROPRENEUR ACADEMY will be the best educational investment you make this year.
I ripped this myself. It's not perfect, i.e. it doesn't include full episode names and only includes the audio versions, but it should be fine if you're listening through the entire set.
I've also included Rob Walling's "Start Small, Stay Small" eBook (ePub, PDF and audiobook.) This is essentially a 'lite' version of Micropreneur Academy intended to up-sell. You might want to skim through the eBook first to see if Micropreneur Academy is worth your time.
