Building Sand Castles

Have you ever sat on a beach, watching children build sand castles? Some know that it will only be a matter of time before their creations are washed away. Others believe themselves to be constructing fortresses, so strong and secure that the sea itself will be unable to destroy them. They, presumably, grow up to be the engineers who make dams and tidal barriers. Give an ocean enough time and it will even erode a mountain. The way to withstand the potential ocean of change is to float, not fight.
