Positive Psychology is not just about research and interesting discussions: changing your happiness levels means doing things you might not normally do. Look at it as an experiment on yourself and your surroundings. After all, we can't expect change if we continue exactly as we have before.
The charity Action for Happiness has created a six week program to boost your happiness. The reason I propose we do this together is because sometimes following through can a bit difficult if attempting change alone. You can find out more here: http://www.dsd.me/dohappiness/
Please only reply with yes once you have signed up for the program. Set the date to start on January 6, 2014 (or later if you join us later). The proceeds go to the charity and I am not affiliated with them.
