Those Who know

In this life there are leaders and there are followers.  There are people who create, and those who cannot.  In every aspect of life though everyone has something, if not one thing they are good at.
"Those who know what and those who know how work for those who know why", means that someone has created something from a thought or dream, imagination if you will, and brought it to life.  They had the means, and the knowledge of the inner workings of the, beast but not quite the entirety of the mechanism.  For that they needed and relied on others who know. 
Albert Einstein once said, "Imagination is more important than knowledge", and I tend to agree with him.  Not that knowledge and learning isn't important, but imagination can take us beyond common knowledge, and there in-lies some of the best ideas.   Imagination is critical thinking and creativity at it's best. 
There are so many times I come up with an idea, but could not tell you how to implement it, or how to go about it, just know how it would work.  I cannot be bothered with the little things like monies, marketing, patents, etc., just tell me how to get me idea off the ground.  And so, it sits.
I read somewhere that it's not that children are little scientists, but scientist are big children, and if you ever had the chance to watch someone with a great mind, you would notice how childlike they are.  Imaginative.  Curious.  Always wondering, thinking, learning, tinkering.  Just like a young child's mind.  Idea's flow. 

That is why, " Those who know what and those who know how, work for those who know why".
