Thanks.<p>I did avoid getting into a definition of what I think an idea is mainly because I wanted the essay to be a catalyst for people to think about their own ideas, not just be another rant.<p>I like to think of ideas and execution as potential and kinetic energy. A great idea is a bolder at the top of a hill, while a bad idea is a bolder at the bottom. Execution is the process of keeping the bolder moving.
