Quantified self

Quantified self is a way to measure and track things about yourself. This could be anything from how many steps you take in a day to how many hours of sleep you got last night. It’s like keeping a diary, but with numbers and data instead of writing things down. Keeping track of this data lets you better understand who you are and how you’re changing. For example, if you track the number of hours you sleep, you could figure out if getting more sleep helps you feel better or have more energy during the day.
