Millions around the globe have been inspired by a final lecture delivered by Randy Pausch, a professor of computer science, human-computer interaction and design at Carnegie Mellon University.

Pausch, terminally ill with pancreatic cancer, gave his earnest “last lecture” to a packed auditorium of over 400 colleagues and students in September of last year. Titled “Really Achieving Your Childhood Dreams,” it is upbeat, humorous and uniquely moving.

Here are some of the parts in his message.

• Brick walls are there for a reason. They 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 people who don’t want it badly enough.
• No one is pure evil. Find the best in everybody. Wait long enough and people will surprise and impress you.
• Never underestimate the importance of having fun. I’m dying and I’m having fun. And I’m going to keep having fun every day because there’s no other way to play it.
• It is not about achieving your dreams but living your life. If you lead your life the right way, the karma will take care of itself. The dreams will come to you.

A book by the same title, based on interviews with the lecturer after the event, has become a bestseller.

Pausch passed away last week at the age of 47. His courage will be remembered and his legacy will continue to inspire many.
