Gardner's rule of point of view

One of the problems with being self-educated is that when people question me about my writing, sometimes I'm not sure of myself. I mean if they question some specific aspect of it. (Say, point of view, for example.) My first thought is that I missed something.

My editor is questioning my use of point of view in my latest manuscript. So I've been on a pov mission lately. Reading everything I can about it (which isn't much.) This is what John Gardner says about point of view : you can do anything, just as long as it works.
