Walls

"Brick walls are there for a reason. The brick walls are not there to keep us out. They are there to show how badly we want something."Dr. Randy Pausch

Randolph Frederick Pausch (October 23, 1960 – July 25, 2008) was an American professor of computer science and human-computer interaction and design at Carnegie Mellon University (CMU) in Pittsburgh, Pennsylvania. He learned that he was terminally ill in September of 2006. He gave an upbeat and adage-laden lecture entitled "The Last Lecture: Really Achieving Your Childhood Dreams" on September 18, 2007 at Carnegie Mellon, which became a popular YouTube video and led to other media appearances. He then co-authored a book called The Last Lecture along the same theme, which became a New York Times best-seller.
