Ideas are useless unless used. The proof of their value is in their implementation. Until then, they are in limbo.
Ideas are commodity. Execution of them is not.
The best big idea is only going to be as good as its implementation.
They spent days, nights, weeks, and years talking, never accepting the fact that, good or bad, an idea only exists when someone tries to put it into practice.
It's the execution that matters, never the idea.
Ideas are easy. Implementation is hard.
The most brilliant idea, with no execution, is worth $20. The most brilliant idea takes great execution to be worth $20,000,000.
Ideas are easy to come by; reduction to practice is an arduous but inspirationally rewarding matter.
