subjective well-being

Subjective well-being (SWB), as Diener et al. define it, is how people evaluate their lives – both at the moment and for longer periods such as for the past year. These evaluations include people's emotional reactions to events, their moods, and judgments they form about their life satisfaction, fullfilment, and satisfaction with domains such as marriage and work
