 Life satisfaction theories identify happiness with having a favorable attitude toward one’s life as a whole. This basic schema can be filled out in a variety of ways, but typically involves some sort of global judgment: an endorsement or affirmation of one’s life as a whole. This judgment may be more or less explicit, and may involve or accompany some form of affect. It may also involve or accompany some aggregate of judgments about particular items or domains within one’s  life.[6]
