Finding ways to grow

Diego Rodriguez of metacool points out an old truth that the past is a rich source of “new” ideas:
“Innovation is about finding ways to grow that are right for you.  Do the ideas need to be new to the world?  Not likely, especially since there are few new things under the sun.  It may be as simple as looking back to times past in search of analogous situations.  People are still people.  What worked then that could work now?”
