How to apply lessons?

Im currently 1100 elo and I have no clue what I'm doing. I've completed a lot of lessons on chess.com and I understand them all well enough, but I have no idea where to focus on when playing a real game. example: i spot a weak pawn and I plan on arranging my pieces to attack it. but after two moves my opponent does something that I have to react to and now I have to abort that plan and deal with the situation which leads to a new mess of a position. Just a very basic example but it gets the point across. I have absolutely no idea where to focus on. There are a million things to consider when making a move and completing lessons only adds stuff to the list of things I need to consider. How to progress from here?

As a diamond member I think you are allowed to sample some of the master level lessons before finishing the core curriculum.  There's a boatload of master level games available.  Maybe it would do you some good to try a few of those courses just to see how pros evaluate positions?  Chess is hard to learn though and having to constantly readjust your plans is quite common and everyone, even experts, finds it a challenge (or so I've read).  And of course if you really can't come up with a coherent plan (or figure out what your opponent is trying to do), you can always fall back on improving your worst piece.

I'd be interested in hearing other's views on this as I'm still very much a beginner as well, but looking at a few losses of yours it feels like you'd do well to focus on your use of pawns and good pawn structure. From looking at a few games you seem to like pushing one pawn out into the board and not moving the rest or setting up a lot of isolated pawns with captures. Eventually the opponent's queen picks it up and ties the board up with their own.

Slow down. It looks like you are playing a lot of 10 minute rapid. Its probably not giving you enough time to think about the position and find good moves.

Hi! My name is Lauren Goodkind and I’m a chess coach based and chess book author based in California: www.ChessByLauren.com.

I have tips to help you improve your chess skills so you can win more games.  

-I recommend playing with a slow time control, such as game in 30 minutes.  You need time to think.  Beginners tend to make a lot of silly moves with very little time.  This makes sense since there’s a lot of pieces on the board.  

 - Before each move,  consider all checks and captures on your side and also your opponent’s side. If you are past this stage, then find a forcing winning line, so you can win material or force a checkmate.  

- Consider hiring a chess coach to help you.   

I hope that this helps!
