Some Quotes from Randy Pausch “The Last Lecture” http: //www. mediabistro. com/galleycat/original/randy-pausch. jpg “Have something to bring to the table, because that will make you more welcome. ” “You’ve got to get the fundamentals down because otherwise the fancy stuff isn’t going to work. “ “The brick walls are not there to keep us out. The brick walls are there to give us a chance to show badly we want something. Because the brick walls are there to stop the people who don’t want it badly enough. ” “Be prepared. Luck is truly where preparation meets opportunity. ”
