I don't know about you, but sometimes I get consumed with the meaning of life and it gets very depressing!  And then other times, I couldn't care less about the meaning of life, and I'm just having a good time.    Maybe it's not good to get too introspective.  For example, look at all the 19th century  philosophers who grappled with the meaning of life.  Their writing is depressing and many of them commited suicide.
