Do not get me wrong, I am learning constantly and like it that way (now I go through a Haskell textbook and have a few MOOCs in my to-do list), but the thing is, I feel like I am still fighting a losing battle; there is just too many new information out there to understand everything. That is the source of anxiety for me.
I very much enjoy working as a programmer, but, to be honest, there is constantly a little anxiety in the back of my mind that I do not get FP/docker/devops/insert-latest-buzzword-here enough not to look like a clueless coder in a watercooler-side chat with a fellow. So I really appreciated this article, it made me feel better about myself :-)
