“What is a worldview and what does changing your worldview involve”
What is a Worldview? Well the dictionary says:

worldview |ˈwərldˌvyoō| (also world view)
noun
a particular philosophy of life or conception of the world : a Christian worldview revolves around the battle of good and evil.


And Wikipedia:
World view
A comprehensive world view (or worldview) is the fundamental cognitive orientation of an individual or society encompassing natural philosophy, fundamental existential and normative postulates or themes, values, emotions, and ethics.[1] The term is a loan translation or calque of German Weltanschauung [ˈvɛlt.ʔanˌʃaʊ.ʊŋ] ( listen), composed of Welt, 'world', and Anschauung, 'view' or 'outlook'. It is a concept fundamental to German philosophy and epistemology and refers to a wide world perception. Additionally, it refers to the framework of ideas and beliefs through which an individual interprets the world and interacts with it.

Me:
The worldview or your worldview, because it’s your opinion what really matters if someone ask you “what is the point of seeing the world? Many things have a roll in how you see the world; Country, Religion, Family, gender, Habits, traditions, culture, hometown, and many other things. Ex:

I’m a guy from Denmark, a small rich country, we are Christians but it’s the fewest people that take the religion serious in Denmark. In Denmark we are very patriotic, we like to put everything that means just for the smallest thing or victory for our country on a pedestal. Yes we are actually very nationalistic. And we are afraid of changes, if it means we have to give something away like soldiers life, Oil etc. I have a wealthy and healthy family and I would never have to go to bed hungry, I got a computer and luckily I was raised by both my blood parents whom is not divorced.
All this have an affect on me and how I see people in other situations, how I see other societies religions etc., and therefore my worldview may be different to a guy in another country, different to my friends from the same town as me and even I’ve got a different point of view on the world than my own mother and father.

My World view: I really think that religion is cool and it explains many things that the humans have sat questionmark to, but then again I think some people take their religion to serious and let the religion take complete control over your life and in some cases destroy it, like Jehovah witnesses: where they have no Christmas, the kids never gets presents, and even if they would like to make changes in their life and convert to Christians, they will get thrown out of their family AND the society. And when Islam with their religion thinks they are so much better and think they have to kill us all to make the world a better place?
If I should look, down from the sky and on the World. I would say the Humans are the stupidest species on earth: We should be the protectors of the earth, and try keep everything cool. But instead we destroy it. And we keep destroying it, mainly because of the Chinese who just don’t want to be friends with the rest of the world, and the American who just are to fat and stupid…


Everybody is changing their worldview all the time, I think one of the main things that changes our Worldview is the media, it’s the only open line to the rest of the world when you sit on your ass in front of the television the bad things about this is that the media mainly focus on bad stuff in the world and that might drive you to too hasty generalizations and if the media only focus on terrorists from Iraq you might think that everyone from Iraq is a terrorist and that everyone from Iraq is dangerous to be in the same room with. Now that is far from true, so it’s important that you don’t let your worldview change too quick and that you can filter the information given to you. Another way to really change your point of seeing the world is in the school and through your education, I think that the school is here to teach is neutral information about the world and teach us how to filter neutral information from opinion filled information which is more likely to take, because then we don’t have to think by our self, the point of view is already given.
