You're confusing two different things, here.
What you say about "psychology" is perfectly true, of course, but it isn't a reason not to read a book about the technical aspects of trading before looking at live charts: nobody can learn how to identify support and resistance without first knowing what they are!
It's very fashionable, these days, especially in forums, to attribute beginning traders' problems to "psychological factors", but that doesn't change the reality that most aspiring traders never make any money because they don't know what they're doing and the trades they put on never have any genuine positive net expectation at all. That's correctable by reading textbooks - not so much by gazing at charts or "mastering psychological factors"!
