To really change the world, we have to help people change the way they see things. Global betterment is a mental process, not one that requires huge sums of money or a high level of authority. Change has to be psychological. So if you want to see real change, stay persistent in educating humanity on how similar we all are than different. Don't only strive to be the change you want to see in the world, but also help all those around you see the world through commonalities of the heart so that they would want to change with you. This is how humanity will evolve to become better. This is how you can change the world. The language of the heart is mankind's main common language.
