I would definitely continue with SQL. Often times we get engrosed in the day-to-day. But I think 98% of us first emerged in the SQL scene based on one thing...interest in this fascinating technology. It most likely wasn't because of the need for a paycheck, although that was a comforting side effect. What first entrigued us (well I can speak for myself) about SQL has only been fortified by a career, but not diminished. Only elevated.
