The author has spent three years collecting over 100 types of data about their life, including fitness, nutrition, social life, and computer usage, and has created a database to store and visualize this data. The project has yielded some interesting insights, but the author concludes that building their own solution was not worth the hundreds of hours invested. The data has helped the author identify trends and correlations in their life, such as the impact of sleep and weather on their mood and productivity. The author has made their data and visualizations publicly available, but notes that the project has not had a significant impact on their life.
