When Wizards asked me whether I wanted happiness or intelligence, I asked for both. I'd like to be smart enough to recognize happiness and enjoy it where I find it. Whether writing a new book or watching the plum trees blossoming down the street.
It seems simple, but sometimes it can be the toughest formula: finding that balance that makes life enjoyable. Writing is one of those activities that does make me happy, whether blogging here or working on a new story. So I'll just keep typing.
Oh, and reading those answers over at the Wizards Community, because the author opinions there always make me smile.
