You may have heard of Marie Kondo, a Japanese Organization Consultant, she wrote a book called The Life-Changing Magic of Tidying Up. In the book she discusses her method of organising, which is known as the KonMari method, it consists of gathering together all of one's belongings, one category at a time, and then keeping only those things that "spark joy", and choosing a place for everything from then on.
I think it could be a cathartic process for your digital life also, what if you gathered all of your digital "things" together, all of the languages, frameworks, libraries, and tools that you use, and decide what to keep from each category. What would you choose?
I think it's more important now than ever to review your "toolset" with this in mind. For your own well-being, you should remove things, keep the "joyful", and slowly add more. There is such a proliferation of new tech, this is a decision you need to take again and again, so it is important to have a good ethos for your personal life and career.
