I'm more interested in learning things that I enjoy, and less interested in learning new things that are new and sexy

Ah, didn't mean to leave the impression that I'm looking for "new and sexy." I just got all fired up learning about JSPs and the other stuff when the client pulled the plug on the project. This does feel like a step backwards after all that, but again I'm not sure how rational that feeling is. Your advice is well taken, and in fact is what my boss has told me: "don't be afraid to try something new." What I'm afraid of is learning something old. I'm already an expert in one language that appears to be fading away (Delphi).
