Ever wonder about rules in photography - rules of composition, focusing, choice of subject, lighting and whatnot.
Truth is, rules are a substitute for thinking. If you don't want to think about how best to frame your subject, you apply the rules of thirds. While a few rules are based on physics and properties of the real world (like hyperfocal distances, most are simply generalizations which work fairly well, most of the time, for most subjects. Is that really any way to treat an image that is important to you?
At the very most rules should be fall-back positions - failing a better idea, then I'll follow the rules but if you think about it, having no clue what to do with the composition doesn't say much for your involvement with the subject matter.
It's entirely different to not be able to decide which of two options is better - framing A or framing B - they may be equally attractive, all be it in different ways and difficulty deciding says more about your personality than either your intelligence or involvement.
Therefore, rules are not made to be broken, they are there to be replaced by careful consideration and should only be used when they explain the physical world or don't have any impact on the creation of the image.
