Why translating?

"I wouldn't do it at all, though, if I didn't find the process fascinating. Getting a phrase just right in the target language is one of those "ah-ha!" light-bulb going on over your head experiences. It's like solving a puzzle and once I get started, I can't stop until I've got all the pieces in the right places. One stroke of genius after another, sentence after sentence."
