Anticipation

According to a 2010 psychological study about the connection between anticipation and happiness that was published in the journal Applied Research in Quality of Life, just planning or anticipating your trip can make you happier than actually taking it. The authors of the study, researchers from the Netherlands, interviewed 1,530 people, including 974 vacationers, and found that the vacationers felt most happy before their trips.
