I recently did an interview with Stephen Key, the author of "One Simple Idea - Turn Your Dreams Into a Licensing Goldmine While Letting Others Do The Work". As the title suggests, Stephen comes up with ideas and lets others manufacture them for him, all while making money.
Stephen goes over numerous aspects of taking an idea from just that, an idea all the way to cash in the bank. In this video Stephen goes over 3 Steps For Ideas for Products
In this Video on 3 Steps For Ideas for Products You Will See:
1. 3 Steps for getting ideas for products
2. One big pitfall in creating something
3. One major way to get costs out of a company
