You can't give up in life
From A Christmas Sermon on Peace (1967) by Martin Luther King
"In 1963, on a sweltering August afternoon, we stood in Washington, DC and talked to the nation about many things. Toward the end of that afternoon, I tried to talk to the nation about a dream that I had had, and I must confess to you today that not long after talking about that dream I started seeing it turn into a nightmare. I remember the first time I saw that dream turn into a nightmare, just a few weeks after I had talked about it. It was when four beautiful unoffending, innocent Negro girls were murdered in a church in Birmingham, AL......Yes, I am personally the victim of deferred dreams, of blasted hopes, but in spite of that I close today by saying I still have a dream, because you know, you can't give up in life. If you lose hope, somehow you lose that vitality that keeps life moving, you lose that courage to be, that quality that helps you go on in spite of all. And so today I still have a dream."
