Chris Dixon neatly captures the “builder” philosophy:

Tim O’Reilly poses a question every entrepreneur and investor should consider: are you creating more value for others than you capture for yourself? …I think of people who aim to create more value than they capture as “builders” and people who don’t as “extractors.” Most entrepreneurs are natural-born builders. They want to create something from nothing and are happy to see the benefits of their labor spill over to others.
