Matt Flannery, the founder of Kiva.org, a microfinance site that brings individual borrowers and lenders together, talks about the process that eventually led to kiva:
I spent a good deal of my time dreaming up new business ideas. I’m the kind of person who always has a new idea, and is always talking about it. I started to have a new business idea every day; 365 ideas was my goal. My friends and family were extremely patient to suffer through this with me.
This is one of the fundamental traits of successful entrepreneurs and it's also the reason why so many successful entrepreneurs have success in more than one endeavor (serial entrepreneurship). The quote is from an article Flannery wrote for the journal Innovations.
