Sometimes all it takes is to refine the way you state a problem to make the solution obvious.

Indeed, I fully agree, my mind functions that way also, in contrast I believe to people like Tesla who had the mental prowess to work out the more detailed and abstract concepts through only an internal "dialog".

I also find it highly valuable to explore concepts and ideas through spoken or written word. If spoken, a suitably intelligent individual or group can stimulate imagination, understanding and creativity. That's one reason I like this social platform, as I find many such people here.
