The 11th-century Persian polymath Nasir Khusraw made a journey of 7 years across the Islamic world and returned not with souvenirs but with a recalibrated self — he'd learned to distinguish between knowledge that merely accumulates and knowledge that *transforms the knower*. This distinction maps surprisingly well onto what psychologist Robert Kegan called 'subject-object theory': most of us are *subject to* our assumptions (we can't see them because we see *through* them), but genuine development means making those assumptions visible — turning subject into object. For a leader, this lands hard on Fridays, when the week's decisions are fresh. The question isn't whether you learned something this week. It's whether anything you encountered actually changed the lens, or just added another slide to the carousel.

Name one assumption you made this week that you didn't question at the time — and trace where it came from.
