Hey LawLover,
Thanks for the message! First, if you are ever scared of reading something, then delay it. There's no reason to force yourself into something you aren't ready for because doing so will probably not have a good effect.
Second, let's talk about the idea of reading these books multiple times, and I'll address this to anyone reading, not just you. I'm not against it, but it depends on how and why you are doing it. For example, if you know you didn't understand something clearly, that's a good reason for a re-read. Or, if you feel like you read it a while ago and want to re-read it again to see what things you missed, that's a good reason. Or maybe you've been taking many PTs and feel like you've become better and want to see how much clearer everything is and pick up hints you missed, that's a good reason. So, if you are -re-reading those books with some of the prior ideas in mind, great. But what you don't want to do is just read the books again and again without doing serious work in between. Once you read any of the books a single time, the best path thereafter is to go out and apply the ideas by doing real games (or drills related to building LG/LR/RC skills). The analogy I'll make is again driver training: once you read the driver's handbook, you have to go drive the car to get better. If you were failing the driver's test, you wouldn't just read the manual over and over, you would instead practice driving (and occasionally you'd go back to the manual to make sure you had it all straight). Thus, the question to ask yourself is: are you re-reading the books for the right reasons, and are you doing enough PTs to really practice the ideas. And keep in mind, you don't have to take every PT timed, or take it to get a final score. You have over 80+ tests out there, you can break them up in different ways and
use them as fits you best.
Last, don't be scared about any of these books
They are designed to be helpful, and the worst thing that could happen is that something doesn't make sense. And if so, we're here to help and try to explain what is being said. So, give the RCB a try, and instead of looking at it as a long book, break it into smaller pieces and read a little bit every few days. You can do it!
Thanks!
