If to-morrow means nothing, and might not ever come, stop thinking about to-morrow. Life's short and meaningless, sure, but does it make you feel better to mope about it? Read a book. Play a game. Watch a movie. Play outside. See the woods. Examine a tree. Play with a puppy.
What is it about that idea that people have such a hard time with?

addition two: 'While wandering a deserted beach at dawn, stagnant in my work, I saw a man in the distance bending and throwing as he walked the endless stretch toward me. As he came near, I could see that he was throwing starfish, abandoned on the sand by the tide, back into the sea. When he was close enough I asked him why he was working so hard at this strange task. He said that the sun would dry the starfish and they would die. I said to him that I thought he was foolish. There were thousands of starfish on miles and miles of beach. One man alone could never make a difference. He smiled as he picked up the next starfish. Hurling it far into the sea he said, "It makes a difference for this one." I abandoned my writing and spent the morning throwing starfish.'
