Just to share a link to tell everyone not to give up.

This link is about a great person who knew he had only months to live (he's already dead, by the way). Yet, he still lived his life then like nothing had happened. He gave a lecture: The Last Lecture. It was really inspiring. I will share 2 links, one is the full version, the other one a shorter version.

That was the longer one.
