Happiness to me is obvious when I am spending time with people I love. Happiness is when, for a split momet, I hear the punchline of a joke and laugh. Speaking psychologically, the adjacent emotion, joy, comes when my identity and ego are not at the forefront of my thought. When I forget about myself as an individaul, I cease to particularly worry about the things that affect me. It's almost like I take a backseat to all the operations, watching my mind and body operate with less mental inhibition.
