The Official Site of Hideo Takeuchi, Ph. D.,

The real truth is I probably don't want to be too happy or content. Because ... then what? I actually like the quest, the search. That's the fun. The more lost you are, the more you have to look forward to. What do you know? I’m having a great time, and I don't even know it. ー Ally McBeal, season 1, episode 1 "Pilot", (FOX TV, September 8, 1997).
