What's next after first 5 months and 700 points? I started playing chess in July. I was at a 600 rating on Chess.com for a month. I started playing seriously in August and have played regularly (at least a few blitz and rapid games everyday). Currently, I am rated 1300 on Chess.com after 800 games(10 minutes). I seem to have moved past my blundering days (although still blunder every now and then). I also play shorter games on lichess (rated 1400 on blitz). 

I haven't really read any literature yet. I started reading Logical chess by Chernev. I play the games out on the board and they are fascinating but I don't see how I can improve with them. Also, I do puzzles on lichess frequently. I haven't seen any significant changes in my thinking process recently when I play games. What's the next thing I should do? 

My goal really is to be able to create and execute longer plans in the game while being able to read the opponents plan and defend. I was told this corresponds to the ~1900 rating range, so that would be my target (rating wise) by the end of 2019.
This is an open-end question. My recommendation is join serious face-to-face tournaments where you play games at the classical time control. Playing blitz is fun, but not a good idea for learning chess.
