So, amidst my online perusing lately I went to a blog called The Happiness Project (http://www.happiness-project.com/).
It's written by Gretchen Rubin, an author currently doing research for her next book on...well...happiness. She's tested out theories and methods for being happy. She has happiness goals and projects going all the time. I don't agree with everything she's written but there are definitely interesting posts. Take a look :)
