QUOTE : having specific things to look forward to massively increases your enjoyment of them. “It extends the experience,” says Cassie Mogilner, a professor of marketing at the University of Pennsylvania’s Wharton School, who specializes in happiness research. “The whole time you’re looking forward to it and anticipating it, you’re getting some of the benefits of the experience itself.” This is one of the reasons why people love vacation travel. You generally have to figure it out at least a few days ahead of time. Indeed, research published in the journal Applied Research in Quality of Life in 2010 found that vacation anticipation boosted happiness levels for eight weeks—an argument for planning more shorter trips rather than a few longer ones. Plan a four-day weekend every other month and the happiness boost could last all year. I know this anticipation factor is why I always have great birthday weeks. Not only do I think ahead of time about what I’d like to do—meeting up with friends, taking the kids somewhere fun, getting a massage—I plan these activities in advance and then enjoy seeing them on my calendar, knowing that tickets are purchased and babysitters are booked.
