You have to know what type of learner you are. Some thrive on reading every scrap of info they can get their hands on so they feel they know as much as they can and that gives them the confidence to move on. OTOH, I read Palmer before going all grain and some parts, like water chemistry kind of froze me for awhile until I just did it. I suggest reading Palmer cover to cover without any expectation that you will understand everything then start brewing using Palmer more as a reference book, re reading the parts you need to actually brew. Once you get a few batches under your belt questions and areas of interest will naturally arise and you will go down your own path.
