It describes the basic reason a human strives to learn more to educate themselves, to drive technology, to innovate and create.  The greatest creators of our generation and past generations have been driven by their need to know.  Bill Gates' impetus was his need to know.  Steve Jobs and his team's motivation is based upon a need to know.  You can bet that Mark Zuckerberg's need to know began in middle school (or maybe even before) when he first started messing around with programming.  Michael Dell needed to know if his idea to build a customized and yet more affordable computer would make him money, it did.  

Our desire to learn, grow, improve, develop, upgrade, install, maintain, establish, and upgrade again all stems from the need to know, the need to keep searching for answers, for the better way.

The better way is always out there, always waiting to be found,  And interestingly enough, once it is found, another better way lies just ahead begging for another search of its whereabouts to begin.  After all, that is what the better way is all about - the continuous search and deliver.  

The advances that occur in our day-to-day lives keep us on our toes.  Finding what you need to find on LinkedIn seems more arduous each day.  Becoming an expert is impossible.  Being a student is imperative, so never stop learning.  That's pretty much all you need to know.
