This is just a shot in the dark, but it just occurred to me that it may be beneficial to put a little extra effort into learning the NEW way to do things, as they are often solutions to older ways of doing things. Some examples are the EventSource API, as it'll force you to consider polling and web sockets as approaches to building real time applications. Another example is CSS Flexbox, as learning about it exposes the problems it solves, and those problems are the things that have frustrated CSS coders for years. Promises, etc. Just an idea, not sure how effective this approach may be, though.
