It seems like a huge breakthrough to realize that you only have to use an approach to the GT that works for you. I think there are so many methods because they've come from lots of different people and it's felt that something is being left out if they're not all mentioned. Still, I'm always surprised how one person will swear by one technique that does nothing for someone else. What if you were only taught one way and it never worked for you so you felt you were a failure? Rana taught me chaining the houses several years ago, and I instantly loved the technique, which has worked well for me, but others see it as a meaningless waste of time.
I worked hard to understand knighting (especially in a Square of 9) and still feel I'm missing something, so I don't do it religiously, but because of all the work, my eye (or subconscious) sometimes picks them up naturally and in a way that actually helps. For instance, I've seen a couple of cases where the Man and Woman cards in a GT were linked through a shared card that both knighted. That card is always an important link in the relationship as discussed in the spread. But someone else might get the equivalent info another way.
