Innovations at work

I have always wondered what innovations are invented , but when i was watching the movie " The Social Network" i felt innovations are simple, its just that we need to work on the simple idea, simple concept which can bring a lot of change... A lot change, few innovations Like Car, Planes, google, you tube where simple solutions for the simple problems, just imagine if some one had ignored working on it???? we would have missed a lot of things... but let me let you that every individual has innovation, but hardly few work on them and spend on them... I need to not like this, i need to work on my innovations... I ll do work..
