In one word: meditate. Sit down in a comfortable position, close your eyes, quiet your mind, and try and free yourself from all sensory stimulation. While there is no guarantee that if you do this you will have psychic experiences, there is a significant amount of evidence suggesting that "meditators perform better in some laboratory psi tests than non-meditators."
Also, while there are a plethora of books out there that claim to be able to teach people how to use psychic powers, the majority of these are under strict scrutiny, as studies have shown that these types of books and programs typically fail. However, there are cases of a few people (such as Malcolm Bessent) who have attended "psychic school" and gone on to perform very well in several parapsychology experiments. It may be that psychic ability is similar to an artistic talent: for those who inherently have that ability, training will help to improve and refine that ability, and for those who do not, there is little that ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
