"Something hit me very hard once, thinking about what one little man could do. Think of the Queen Mary — the whole ship goes by and then comes the rudder. And there’s a tiny thing at the edge of the rudder called a trimtab."

      |  R. Buckminster Fuller

trimtab:

      a comprehensive strategy, that is conceived in such a manner and strategically placed into the prevailing system at such a time, in such a place, where its effects can be maximized, thereby creating the most advantageous change with the least amount of resources and energy on a relative basis.
