I learned this lesson: focus on mastering the language and understanding the fundamentals of networking instead of chasing new shiny web frameworks.

Web frameworks come and go, but the language and network protocols are here to stay.

Learning the fundamentals does pay off in the long term. I've not worked on web apps for a long time but this week helped some junior colleagues set up a web proxy to do SSL termination and explain there's these things called caching servers that can vary and probably solve a lot of their performance issues. I didn't know or really have to care what frameworks they are using.
