Randy Pausch's Last Lecture

Randy Pausch's speech is so inspirational. One thing he teaches is that there are "brick walls" that show you how much you actually want something. Sometimes they're flesh; other times, not. They show you who really want to achieve something and those who don't and they let you push forward.
He thinks and teaches that you should have fun while learning. With his projects, his students didn't know they were learning anything because they were having so much fun with everything they were doing. The main thing he wanted to have was fun.
He also teaches you to never give up. He didn't get into Brown or Carnegie Mellon, but he found other ways to eventually be there. If at first you don't succeed, try again. He also believes that you should always tell the truth and to help others along the way. You should always apologize and you should focus on other people, not just yourself.
He also teaches that you shouldn't complain and you should just work harder. Also, take the feedback that people give you and don't fuss about it. Put it to work. I think his main thing is just to not ever give up. He didn't, that's for sure.
