There’s a book I read a while back, Comedy Writing Secrets by Melvin Helitzer. When I read it, I didn’t do so in order to memorize it, but more because I found it interesting. Like watching a documentary, you’re usually not doing that with the intent of memorizing it.
Afterwards, even though I didn’t remember a thing consciously, I started recognizing situations that would fit certain styles of comedy. I couldn’t tell you the specific name of that style of comedy, but I was able to apply it.
So I read it again. And again. Every time without any goal to memorize it. And every time afterwards I started seeing more and more funny things in life. Nowadays I can be the life of the party at a funeral.
Same goes for the Laws. Some non-conscious part of you observes a situation, remembers the description of a similar situation from the book and associates the current situation to that. Which in turn is linked to the law/lesson. At this point even though you don’t know exactly why, you are effortlessly guided into applying the law.
In a way, that’s how PCC probably works. It stores the book away in subconscious memory to be applied automatically.
I too like the idea of running PCC while reading the book, but that’s mostly because it seems a fun and interesting thing to do. Maybe it’ll be even more effective that way.
