I recently talked about your ideas being worth 2 cents and Jackson Miller's story.  Turns out there's a better offer out there and its been scientifically proven.   Fellow start-up bloggers Bradley Joyce and Alexander Muse both found evidence that ideas can be worth $20. Why $20 and not 2 cents?  Here's the "formula". What does it all prove?  I think if you take all these posts and their arguments together it shows that ideas are essentially worthless without execution. So if you're an "armchair entrepreneur" (not referring to someone who starts a business selling armchairs) or borderline disgruntled corporate cubicle occupant, spending many hours sifting through potential business ideas, stop!   Spend no more than 5% of your time picking the idea and the other 95% on executing the idea.  The idea part is the dreaming, the execution is the building.  Build. Build. Build.
