I too am in the same boat. I too am overwhelmed by the amount of information out there. Currently what I do is, I make content, and to make content, I need to learn. Also, If I take up any online class, I make sure there is a certification awarded. Another thing I do is always try to do something that adds the green square in my github profile.

In short, if you produce more, you will automatically learn more.

Now, what to learn depends entirely on your choice, also for me, I am Ok to quitting if I don't like any course.
