There's a particular kind of chairside stress that every one of us knows: the shade guide fan spread across the tray, three or four composite kits stacked because none of them alone covers the shade range you need, and your patient watching the clock while you cross-reference A2 against C2 against "somewhere in between the two." It's a small moment in our day, but it repeats dozens of times a year, and over a career it adds up to something bigger than lost minutes. It turns into a system that's working against you.
