What you do for others around you, you do for yourself. What you do for others around you, leads them to do for others around them, which, like a boomerang, will end up benefiting you and those you love as well. We are all here for each other, and we all affect each other, whether we realize it or not. The more you do for the good of the whole, the better the world will be.
