I think a lot about happiness - what makes a person happy, whether or not happiness should even be a life's priority - things like that. A good high school friend stunned me at the early age of 17 by suggesting we should not necessarily try to be happy. Sacrifice, service, devotion to a cause were higher orders, he felt, although presumably, since those were choices, their pursuit could secondarily lead to happiness.
I traveled once to Africa, as you might have guessed by now, and it's been a part of me ever since. Being perhaps the cradle of civilization, if not life itself, Africa casts an eerie glow over the entire history and, indeed, meaning of existence.
