Hello Zofia,
Congratulations on having passed levels one and two of the CFA exam. Whew! Almost there! See my above answer to Jorge for some book ideas.
Advice for streamlining your focus: as I described up above I would spend serious time in quiet contemplation sorting out how you see the world. Try not to reference other people's thoughts. In other words, try to get to the heart of what you personally believe instead of, "I'm kind of a value investor like Graham and Dodd, but I disagree with them here." Instead, think about your disposition, are you quiet or gregarious? Does your consciousness evaluate short-term things better than long-term things? What do you do and enjoy that triggers a zeal for discovery? Does looking at the macro economy before looking at individual businesses make more sense to you? And so forth. Once you know that about yourself then you can unequivocally throw yourself into the pursuit of what you want.
I hope that was helpful!
Jason
