One of the small yet positive habits I have adopted this year is mood tracking. Exist is a “quantified self” service with lots of features, including an easy-to-use mood tracker with a single 1-5 rating and a short description field. (A couple of years ago I reviewed Exist, if you’re interested in learning more.)

I love discovering surprising correlations in my data, like my mood spiking on days I have public speaking engagements. For many years I tried to convince myself that I didn’t enjoy public speaking because so many people I know despise it. It seemed wrong to enjoy something that must be awful. But I do enjoy it, and it was mildly vindicating to see that so obviously in my mood data.

Have you ever tracked your mood with an analog or digital tool? Why or why not?
