Well, first of all, new shiny things are not really new at all. The principles behind them have been around for decades. Learning 30 different imperative languages (c, pascal, ada and descendants) might not add as much value as learning an imperative language, a functional language, a logic programming language, a language emphasizing concurrency (go, erlang), etc... meaning, learning paradigms and high level design constructs not syntax. Try to stay in touch with new paradigms, instead of just new applications of them.
