This is the short presentation I gave at The Boston Quantified Self Meetup Group #3 in Cambridge, MA: http://www.meetup.com/bostonQS/calendar/14132216/ In it I explain what I think is missing from the self-tracking data movement, why it needs to be part of a personal scientific method, how it makes you happier, and a little about our edison (tm) Experimenter's journal tool to help live everything in life as an experiment: http://edison.thinktrylearn.com/ Give it a look and let me know what you think! It's my first take, and I'm developing the ideas as I write my book, "Think, Try, Learn: A scientific method for discovering happiness."
