If someone thinks it's a good idea, they'll invest money into it. Rough parallel, but always remember: it's not a principle unless it costs you something.

I'm not sure that execution always trumps ideas, but I'm pretty sure that no "great" idea is static and any idea requires more than just potential energy to turn into anything--plus, I'd be way more interested in the personality and abilities of the person presenting the concept than what the concept itself. Chances are if they have sufficient confidence and endurance to plow through the inevitable challenges, they won't ask your opinion.

Simplified (not necessarily) simple concepts tend to work the best. Sounds obvious, but you can't always complicate to profit.

Years ago, before taking my first job, someone told me that the keys to success were pretty simple: persistence, commitment, and patience. I thought I had the first two wrapped up neatly, and would eventually find that "patience" thing. Turns out, I had NO idea what persistence meant and didn't understand the first (or second, or third) thing about commitment.

You don't learn about those things by having a few good ideas. You learn about them by doing things, over and over again.
