This helped me: Nobody asks a professional violin player to "just" switch to the cello, because the orchestra is missing one. Yes, there are many musicians who are proficient in multiple instruments, and yes, the underlying music theory is the same and maybe even the playing mechanics might be very similar (e.g. within strings or winds). A few years ago I made a conscious decision that - at least during my remaining professional career - I will not switch to a new programming language anymore. Instead, I intend to keep specializing in Java. I embrace the fact that in 20 years I will be today's (Assembly|Fortran|C|...)-specialist. I do enjoy reading about other language features. I applaud the people at the cutting edge, experimenting with new stuff, and I am glad that Java is slowly incorporation some of those innovations. Every LTS release (2-3 years), I enjoy learning the curated set that Oracle's language architects decided to add. This decision helped me tremendously with the fear of missing out on the latest and greatest.
