Feel interest, joy, arousal, excitement, and a sense of opportunity when given a difficult challenge that offers immediate diagnostic feedback about your performance.  Feel happy when pursuing goals such as winning, diagnosing personal competence, and improving the self, as often happens in sports and various domains of risk-taking (e.g., investing in stocks, entrepreneurship). You feel excited and energized by standards of excellence and when evaluating your performance against personal standards.

Feel calmness accompanied by warm, positive affect in situations that offer comfort and interpersonal security (Wirth & Schultheiss, 2006). Feel happy when pursuing activities such as cuddling (family in bed together on a Saturday morning) or just relaxing with a close friend at the coffee shop or beach. You feel a calm, satisfying joy when you are in close contact with others and when forming and maintaining positive personal relationships

Feel strong, sharp arousal spikes that generate a burst of epinephrine, testosterone, and increased blood pressure and muscle tone (Hall, Stanton, & Schultheiss, 2010). Feel happy when pursuing activities such as riding a roller coaster and making a persuasive speech in front of a large audience. You feel strong and empowered during social influence attempts, when attaining high social status, when in a position of leadership, and when dominating and directing others.
