I am not as experienced as you are but I do spend a lot of time learning new frameworks. As with everything new the more time you spend with it the better you get.
Rather than trying to learn a thing inside out I like to pick stuff that can be immediately useful to me and build some small stuff with it.
For instance I am learning lua (and open resty) at the moment now lua is itself a very small language but I am new to it none the less. I tried reading a programming book but I got bored quickly as it repeated almost the same stuff that I have gone through many times before(operator precedence etc).Instead I created small utility apps that were useful to me immediately.
Like I created a lua script that cd-ed into a directory and started an elastic search server. Another one that abstracts couchdb api into quick command line options (I got tired of typing long curl http requests into the terminal) and does other things like replication pushing design docs etc.
I use books as reference, something to come back to, unless there is a book like learn you some erlang which I read cover to cover :)
