Happy (adj); encompasses living a meaningful life, utilizing your gifts and your time, living with thought and purpose. It's maximized when you also feel part of a community. And when you confront annoyances and crises with grace. It involves a willingness to learn and stretch and grow, which sometimes involves discomfort. It requires acting on life, not merely taking it in. It's not joy, a temporary exhilaration, or even pleasure, but is more accurately defined as being content.
