Graduation is when school stops making you learn. That’s exactly when you have to start choosing to.

School supplies the pressure, the schedule and the consequences, and when it ends all three disappear at once. The default after that is zero, and zero is comfortable, which is why so much learning stops at the exact moment it becomes optional. Nothing announces it. It happens quietly over a year or two.

Build your own version of the structure that was removed. A fixed evening, a book you have to finish for someone, a course with a date on it. What you learn after this point is not assigned, which makes it both more useful and more yours.
