Damn it, I so wanted to say 42...
But really though, to me, life is what you make of it, there's no real definition and meaning to life, I personally believe that, one way or another, the meaning to life is whatever you can come up with, make it your own and don't just follow some universal rule, live life to the fullest and enjoy it while you can.
Well, at least that's my view on life's meaning, make up your own, that's the beauty of a question with no answer, you're well within your rights to make up your own meaning to life.
