The camera that made me slow down

A Yashica FX-2, or one very like the one I learned on. Nothing automatic, and no screen to check. That's 36 chances per roll, and you find out a week later whether any of them worked.
Which camera changed how you shoot?

A cheap 35mm prime on a very old digital body. Removing the zoom removed about half of my bad habits.
