There are two ways you encounter things in the world that are different. One is everything that comes in reinforces what you already believe and everything that you know. The other thing is that you stay flexible enough or curious enough and maybe unsure of yourself enough, or may be you are more sure of yourself - I don't know which it is - that the new things that come in keep reforming your world view.
