At the beginning when I saw the title of your post, I thought it would be about the usual stubborn attitude to the idea of changing one's way of thinking. People with destructive believes often oppose the idea of changing them - since the idea of changing your way of thinking is often countered by catchy "accept yourself as you are instead of changing yourself"

But (the very different thing) that you actually wrote about is also just as true.
Way too often people retreat to searching for the change in the external world as means of finding internal peace in themselves. In my humble, amateurishly-psychological, theory I think comes from the general consumerist culture that we live in (advertisements making us pursue materialistic goods in order to achieve happiness - which, happiness, in its nature, is an internal, not external, matter).
Good post, I liked that. Thanks.
