I would interpret this as "stop following rules and stop doing things you know it works."

All those rules, like rules of the third, not put horizon in the middle, etc, etc, etc, if you follow them every time, you get good photographs each time. But none of them will be great photographs. None of them will be uniquely yours. Many of them will be like many others that has been done - well, many times!

If you've always done certain things - like certain subjects, certain view points, certain -whatever-, consider changing. Do something else. Do something that might or might not work. Discover something new. I think your images have become too deja-vu.

Either that or your instructor wants you to stick your head out of your sunroof while driving at 100mph and take photographs.
