Well it all depends on the person and what THEIR truth is. Everyone's truth is constant, which is why we all argue so much against each other because we just SWEAR that our way is right and that the other person's way is wrong simply because their way didn't work for us whereas the way we currently do things is better. But that's because it works better for us due to what type of person we are, the type of people everyone else is, the environment you are in and grew up in, your mindset, etc. The truth is constant, but only per its environment/scenario. Let's consider a very basic chemistry equation:
For the environment of A + B ⇌ C + D
K = [C][D]/[A][C]
K is the constant, or your truth. Now A might be the variable describing what your personality is, B could be your natural intellect, C is the schooling you were actually given, and D could be how you were actually raised. Now let's say that for each of these, you give a number that represents the way you were raised or how much schooling you were actually given, etc. Each person is different, so each person's numbers will be different. What happens then? The result is that everyone has a different constant, which is means YOUR truth differs from everyone else's. Some people have more variables than others, meaning some people have factors A, B, C, and D affecting their life and who they are, whereas some people have A, B, C, and D along with E, F, and G. Some people might only have A, B, and C to account for why they are the way they are.
This is getting a little bit weird and abstract but hopefully this makes sense to everyone. People just needs to remember the basic rule that what works for you might not work for others and that what works for others might not work for you. That's why after a while of being 'in the game' you start to notice that you can bend some of the rules and even break them to fit your own agenda and women will still love you for it—that specific situation could have only happened with a specific truth. It's dependent on each person because of who they are and what the environment they're in currently is, and as we can see, there's WAY too many factors to take into consideration to determine what will work 100% of the time. And sometimes, all the factors could be differing to their degrees (say different numerical values for A, B, C, and D) but the K value still remains the same as it was before, meaning the truth, YOUR truth still remained the same. That's also why they say there's no one single magical method to attract women, rather a whole bunch of different tools to add to your toolbox instead.
