I used this last year when it was launched on PH, I spent hours filling out the form as honestly and detailed as possible and I can say it absolutely helped me identify the painful, the helpful and the hopeful parts of 2017. Which in turn helped me effectively plan my 2018 with a handful of goals and habits that I wished to establish. Now a year later I can say that the goals and habits that this project helped me discover are still in place.
I hope that this can be localized to an app or hosted website that I can count on using yearly, or even quartearly.
