Read!! All you can. Don`t just settle for an oppinion until you know all there is to know about the subject.
And question your beliefs even then.
But keep reading! Only this way you`ll be able to actually ‘see’ the box that limits human mind.
The reality is greater than fantasy. If you doubt, just read Da Vinci and Jules Verne, and then look around what happened in less than half a milenium.
