Based on the latest scientific research on happiness a group based out of the United Kingdom has identified ten "keys" that tend to have a consistently positive impact on people's overall happiness and well-being. The first five keys relate to how people interact with the world outside, while the latter half are concerned more with the inner life. This piece shares the ten keys (that together form the acronym GREAT DREAM), and also includes thoughtful questions under each key to prompt self-reflection.
