cheap is talk
The world is divided in listeners and talkers. Those who talk think and have you believe they know everything but in reality they know nothing, those who listen think and have you believe they know nothing but in reality they know everything.
It's those who talk who have all the good ideas, there is plenty of room for it in their head. Passed the point of talking the ideas have little hope to become reality in their hands.
It's those who listen who have no ideas at all, their head is full of everything everyone else is talking about. They can see the quality of the idea in contrast which makes it easy to pursuit.
It's probably a good thing the talkers cant recognize the gems in their own ideas. Just imagine the arrogance that would generate.
ok enough talk....
