A Secret Idea
The way to tell a seasoned entrepreneur from a rookie is how secretive they are about their ideas. Seasoned entrepreneurs know that ideas are a dime a dozen. To find someone willing and capable of executing on it, however, is rare. The rookies on the other hand, are under the false belief that they should keep their ideas secret since they believe it's the "secret sauce".
Thus seasoned entrepreneurs talk about their ideas quite freely. An idea discussed and spread is likely to improve. Thus it is probably favorable for entrepreneurs to talk about them rather than keeping them secret. So if you want to change the world, you probably want to get your thinking out there in any way you can, even if it means spilling some secret sauce.
