For me it wasn't any course that changed my whole outlook. It was one dive. One dive with a mentor who due to physical issues no longer dives. He took me on a tour of one of our local sites. One hour dive, I counted eight course changes, and he brought us back within ten feet of where we started. Vis was the usual 10-15 feet or so. But it was his pace - slow and measured, attention to the compass and natural features, and precise turns that did it for me.
That's how I try to teach all my courses now. No rushing or hurrying. As much time as the student needs and as much time as I feel it takes to get all the knowledge I want to convey to the student.
And it is not always in a course that ends up with a card. Often it's done via tailored workshops where I have listened to what the student wants to do and then set up dives, exercises, drills, and even create classroom materials from different sources to do that.
