Read it again till it sinks in, also find "You and your research" and read.
BTW, don't forget this
"There is another trait that took me many years to notice, and that is the ability to tolerate ambiguity. Most people want to believe what they learn is the truth: there are a few people who doubt everything. If you believe too much then you are not likely to find the essentially new view that transforms a field, and if you doubt too much you will not be able to do much at all. It is a fine balance between believing what you learn and at the same time doubting things. Great steps forward usually involve a change of viewpoint to outside the standard ones in the field. "
I suspect you are suffering from this. The only place I look for absolute truth is mathematics. When people write, you must pull out and find your own truth. Don't be upset about it if it doesn't fit your thinking. It's entirely possible to disagree with all of it and yet find it incredible useful.
