Frankly speaking, I don't think my vision can be changed soon. It needs to accumulate experience and knowledge, and it also needs to experience and feel by itself. There are only two ways I know, one is reading, and the other is trying. What classics to see, what to pay attention to, classics. Look at the current affairs reviews and see how those big cows look at world events. Read some professional books properly, not your major, any professional book will do. Expand knowledge. Try something you've never done before. Do anything imaginable and useful within the limits of the law. Trying new fields and new things can bring changes and new experiences.
