So, a slightly different perspective. I like working in a language that I enjoy, that is expressive (I can think in it), and on projects that I started. If it is a bad language, if I am fumbling through it, and I'm plowing through some one else's bad code, life is a slog. There is possibly some middle ground, where a new language or environment is fun and educational. Just so you're on an acceptable learning curve, not burning out.
