“Eric Greitens says that there are three primary forms of happiness: the happiness of pleasure, the happiness of grace, and the happiness of excellence5. He compares them to the primary colors, the basis on which the entire spectrum is created. The happiness of pleasure is largely sensory. It’s a good meal when you’re hungry, the smell of air after it rains, waking up warm and cozy in your bed. The happiness of grace is gratitude. It’s looking over to see the love of your life sleeping next to you and whispering, “thank you.” It’s taking inventory of what you do have. It’s when you speak to something greater than yourself, expressing humility and awe. And then there is the happiness of excellence. The kind of happiness that comes from the pursuit of something great. Not the moment you arrive at the top of the mountain and raise your fists in victory, but the process of falling in love with the hike. It is meaningful work. It is flow. It is the purpose that sears identity and builds character and channels our energy toward something greater than the insatiable, daily pursuit of our fleeting desires.”
