It isn't the billions of ideas, that pop up in the minds of humans around the globe that make money. Very few ideas are worth the time it took for the thought. Most ideas are fleeting 'sparks' that go no place and are forgotten before the next day. Of the ideas that are very good, very few are followed up and ever end up as a worthwhile development in the market place. Most people are just not oriented to do anything about their ideas, while others believe it would take too much of their time or leave them open to others taking advantage of their original idea and benifiting themselvs.
