I would have to say a lot of things we did for EMT training seems like stupid things to learn or work on at first, but then paid off big time. A good example would be "how to move a stretcher" or "how to use a stair char" (essentially a wheelchair built to be picked up and carried). They seem so easy and self-explanatory at first, but the moment you put your hands on them, you're like "wait a minute, what am I actually do here." So it was invaluable to get a lot of hands on time with honestly the two most common things an EMT uses in their day to day routine.
