Different Approaches to Self-Tracking

Self-tracking can be approached in two distinct ways. One approach is looking for the device to dictate how one should feel and behave, aiming at peak productivity and optimization. The other approach involves a more introspective and self-reflective mindset, using self-tracking data for personal reflection and understanding, termed as 'personal science'. Overall, self-tracking tools can empower individuals to take control of their lives in diverse ways.
