If execution is all that matters, your idea isn't good enough :)
Ideas are very important.
1. Without an idea there is nothing to execute on.
2. Depending on how much you believe in the idea it is what will give you the stamina to continue no matter what obstacles you will meet. (This can some times be a problem, but often and advantage)
3. Without and idea there is nothing to validate against.
I don't know about you but in design I always found it a lot more effective to have an idea before i start designing instead of just make it up as I go.
