Do Resolutions or Goals Make You Happier?

Gretchen Rubin is working on a book called The Happiness Project, which is all about how she spent a year trying everything she’s ever heard of to be happy. She’s been blogging about what she’s learned in the process over at HuffingtonPost. Her latest entry is about the difference between a resolution and a goal, and whether achieving one or the other leads to happiness.
 
She argues that having a goal and striving to achieve it is essential to happiness, though many of the things that we talk about as goals—getting more exercise, eating better, avoiding procrastination—are really resolutions that are meant to be kept every day.
 
When it comes to resolutions, Rubin argues, it’s different because you’re challenging yourself to keep that resolution every day as opposed to constantly looking towards an endpoint. “Each day, I try to live up to my resolutions,” she writes on her blog post. “Sometimes I succeed, sometimes I fail, but every day is a clean slate and a fresh opportunity. I never expect to be done with my resolutions, so I don't get discouraged when they stay challenging.”
