Here is a list of books and videos that have affected my way of looking at the world. Some of the older ones can be found for free because they are in public domain. I strongly suggest checking as many of these out as you can if you haven’t already.
In addition to these books there is a list of websites and news feeds at the footer of this website that give alternative news and ideas for you to consider. Using these sites will give you a chance to use some critical thinking and open your mind.
