The squeegee of window washer Jan Demczur is in the Smithsonian. It got there because of his determination and willingness to use what was handy on the morning of September 11, 2001.
The Polish immigrant was riding in a north tower World Trade Center elevator when a hijacked plane hit the building. The elevator came to a stop on the 50th floor. That's when Demczur and other stranded workers preyed open the door, revealing a solid wall.
Rather than give up, Demczur used his brass squeegee handle to hack away at it. He eventually broke through the wall and lead the group to safety just moments before the tower fell.
Got a wall to break through in your life? There's probably a tool at your disposal that will deserve a place in the Smithsonian if you are willing to work with what you've got and refuse to give up.
