Pretty sure you've already received the best advice you're going to get here! Perhaps the best thing I can say is to focus on something until you get pretty comfortable with it. The key to becoming a true master on guitar is to be able to then integrate what you already know with something you are just learning. For example, you can work on alternate picking and do about 1000-2000 reps of a a couple different exercises for a week, then the following week you work on hammer ons and pull off exercises, but then learn how to mix those exercises with your alternate picking exercises.

I know in the title you posted that you're working on chords and rhythm, but this example can relate to what you're doing as well. hope this makes sense!
