Why Use This Tool
Generational identity (Gen Z, Millennial, Gen X, Boomer) shapes cultural references, shopping habits, and social trends. Meanwhile, the "Life in Weeks" concept — popularized by writers like Tim Urban — offers a powerful visual perspective on time, helping people reflect on how they spend their limited years. Both tools combine curiosity with genuine self-reflection value.
