I think it is important to balance between how much new things you are learning and how much you are using previously learned things. The challenge is to squeeze in the most potentially useful new things to the limited set that you are going to learn. For example: is GO or Rust going to be the language that I can use in my projects at work in the future? Should I learn Clojure or Scala? Should I learn machine learning or statistics? etc.

I balance these based on the things I would like to do in the future. I become and learn what I would like be and try to find a job where I can use those new skills.
