Well, for me, it certainly wasn't 42, as Douglas Adams tried to convince us, but perhaps the meaning of life is not so complicated after all.
Perhaps it's about a focus on compassion (i.e. as Roman Krznaric wisely points out, helping others trumps self-help, or rather, the latter flows from the former), combined with the Aborigines' kanyini, with Gandhi's sarvodaya, with Csikszentmihalyi's flow and with Joseph Campbell's towering idea that, in all indigenous cultures, and in all happy people, no need is felt to travel and battle towards a "holy land" overseas; rather the sacred can be found in the connectedness with the here and now, in the ground below our feet and in this moment in time.
