IMHO, (In my humble opinion), books aren't very good resources to use. I read something that said people that are good at solving chess problems, aren't too good at a full chess game. My suggestion is to just keep playing! Play against yourself (just don't take one side or another), play with your friends, play online ect. ect.

I love to play against myself. That is how I got to where I am right now (co-champion of my chess club). Normally what I do is I come out on one side with my standard move. Then on the other side I expirement. I do something different (sometimes very unorthodox) change something ect. Again, don't take one side or another.

Hope this helps.
