Sometimes it can feel like the world is a garbage place full of garbage people. But while humankind is often prone to selfishness and self-centeredness, there are plenty of good, kind, and considerate people out there who go above and beyond to help others in need. Not only do these people make a difference in the lives of those they helped, but their acts of kindness give us all a little boost of serotonin, reminding us that there are good people out there, and inspiring us to be better ourselves.
