Agile is ADHD coping mechanisms application to groups. Small steps, frequent measurements, body doubling, regular reminders about the actual goal, etc.

It wasn’t even a project management tooling originally, but a way to ensure bidirectional information flow and continuous course correction. When goals start deceptively simple and get adjusted as data emerges and feedback gets collected, you can either sit in paralysis or start checking off tasks you know about. Applies to cleaning and developing a payment system alike.
