What does eustress mean?
Eustress is defined in the model of Richard Lazarus (1974) as stress that is healthy or gives one a feeling of fulfillment. Richard S. Lazarus (born March 3, 1922, in New York, died November 24, 2002) was a psychologist who began rising to prominence in the 1960’s, when behaviorists like B. F. Skinner held sway over psychology and explanations for human behavior were often pared down to rudimentary motives like reward and punishment. In that world, love or sadness existed, but were considered more ornament than underpinning.
