I'd encourage you not to look at this as a sole quest. Ideas are easy and have little value until executed. Most creative people are more than willing to share great ideas that they have no intention of executing. The abundance mentality that made them successful also makes them willing to share great ideas. Being around these people either in person, at conferences or even through blogs and videos will expose you to new ideas that have already been thought through and vetted by an expert. As an example Gary Vaynerchuk is always sharing ideas on his videos. Even though millions of people watch it, few probably take action to make it a reality.
