Take some time out today and read this article on thoughts from a dying man, professor Randy Pausch. An excerpt:
So what did Pausch actually say that day? He spoke about the brick walls that often appear in the path of every accomplishment. "Remember," he said, pacing the floor, "the brick walls are there for a reason. The brick walls are not there to keep us out. The brick walls are there to give us a chance to show how badly we want something. The brick walls are there to stop the people who don't want it badly enough."
