What a mess

I feel like I've stepped into a swamp. The appendix introduced so many new ideas and didn't contain enough explanation and recapitulation. I don't know whether it's because of my poor comprehensive skills or the author's unclear writing. Anyway, this reading experience hasn't been pleasant. My thoughts are muddled. God! Thinking is hard; but fortunately by doing so you'll always find a way to go about the issue. First I have to understand the material, then analyze it, then find out the weak spot to attack, then articulate it. In this case, my problem lies in the understanding process. And I'm focusing on tackling this particular problem. One  step at a time.
