Thomas Wolfe along with many other writers have said, "You can't go home again." The idea of this phrase is that once you have had your world view changed by outside forces, such as travelling to foreign and distant lands, you will never see home the same way again. You will have changed. Your eyes will be opened to new possibilities. You will have new insights on the things that you do and the reasons for doing those things. You will see that it is quite possible to do tasks in new and different ways, that cultural understandings are different from here and there. You will have changed while you were away.
