39. 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 how 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.”
