It’s a great practice for Agile teams to keep a happiness metric to help teams improve their teamwork to create outcomes. Dips in happiness can be a sign that something is amiss in the team, and usually shows up before velocity and product quality starts to trend downward.
But does the same idea work for an individual? I think the answer is yes! Here’s my data from mid-February to mid-May 2019.

To help me calibrate this measure, I used a -3 to +3 scale. This provide a true midpoint (0), so it’s more clear on what’s happy or unhappy. I recorded this measure each day. The red dotted line is the moving average of the previous few days.
Agile Best Self Principle #7: Investing the time in yourself is the primary measure of progress.

Agile Best Self Principle #6: The most effective way to be your best self is to be mindful and intentional.
As a data guy to the core, seeing this data visualized really provided powerful insight. When I spend more effort living my vision, the happier I am overall. Sure, there are still bad days — life does happen. I think the time spent unhappy is also reduced. Nevertheless, the trend is positive. It is possible to “turn up the good!”

Brian, you are absolutely a ‘data guy to the core!’ This is a great introspective tool and trending tool. I use more of a journaling approach to tracking things. But I did include some data for you on one of my blogs.
