Why do we view the midpoint of our projects as a make-or-break moment?

I recently came across a couple of posts from Robert Meza describing 👨🏻‍💻 Andy Budd’s The Reverse Double Diamond (https://lnkd.in/gh7G4dyh) and Azzen Abidi, who shares 37signals Hill chart (https://lnkd.in/gZtVWusF). Both are fine ways of solving problems, each adding its unique variation to the linear progression of a project.
