Do you consider yourself an open-minded person? If so, how do you know if this is an active truth, or if it is merely an opinion that you have of yourself? It's a very intriguing question to ask, and what it will ultimately lead to is you questioning what your cultural integrity is like, especially as related to the world or the people around you. As an example, think of going through with these following options and activities so that you demonstrably broaden your worldview. Perhaps you want to go on an educational tour at some time to allow someone else to present you with practical information. Maybe you want to learn a new language. Perhaps you should start spending time reading more world news as opposed to just sticking with what you're already familiar with. And finally, if you check out discussion forums where people from other cultures talk, you can learn a lot simply by observing those processes.
