Ideas- nope. It's all about execution.
Ryan Allis, the 19 year old genius entrepreneur wrote a great article on execution of ideas.
"In 1967, an angel investor, Fred Adler, received over 50 business plans for entrepreneurs who proposed to start microcomputer firms. Only one of the teams presenting this idea ever made it. Its name was Data General. But why did so many entrepreneurs pitching a plan to sell microcomputers either never receive funding or if they were funded, never succeed?
They didn’t make it not because the idea was per se bad or didn’t have the potential to be a good opportunity. It was a great idea and enormous opportunity. Rather, it was because the other entrepreneurial teams were unable to execute."
If you enjoy reading, I highly recommend the book Execution: The Discipline of Getting Things Done.
