I like that for the soundbite aspect of it in relating to not taking things personally, but I have to say I don't see anything wrong with seeking a purpose in existence. Humans have always striven to reach beyond the randomness of life, and will always look outward for answers to the unanswerable.

Also, quoting Richard Dawkins is not a way to get on my good side. Not because he's an atheist, but because he denies the necessity of fancy and imagination for happiness.
