The honest math

Nobody wastes a decade on purpose. It goes 4 hours at a time, every day, while the gym membership idles and the book stays on page 40. The point of the number isn't shame—it's that you can't negotiate with a fog. Put a number on it and it becomes an opponent you can fight.

Your word is your weapon.
