The "Quantified Self" movement involves individuals tracking various aspects of their daily lives using technology. This can include monitoring physical activities, sleep patterns, diet, and even mood. By collecting and analyzing this data, people aim to gain insights into their habits and improve their overall well-being. Many tools and devices, such as fitness trackers and mobile apps, facilitate this self-monitoring. The goal is to empower individuals to make informed decisions about their health and lifestyle. The movement encourages a data-driven approach to personal development, fostering a deeper understanding of oneself through measurable metrics.
