I have a few red pill books that I intend to study in depth and read multiple times. Is it advisable to stick to one book at a time?

I say this mainly because I am itching to read Models but feel an obligation to study How to win friends and influence people (we should start acronyming that book - HTWF) as in depth as possible before moving on. What do you guys think?

I'm afraid that this is a really dumb question but I haven't been much of a book reader in all of my 17 years.
