The short answer is no your aren't the exception to the rule. So how do you know if that writing advice directly applies to you and your manuscript? Odds are it does. However, there are times you may want to ignore that tip. But should you?
When it comes to writing and subjectivity there is no quick yes or no answers, but there are some things you can ask yourself to see if you should make use of that tip.
1.) Are you doing it deliberately?
If you are making a conscious decision to ignore a writing rule and you know why you are choosing to do so, you might be the exception. MIGHT. However, just because you are aware of what you are doing doesn't mean it puts you in that small percentage. Make sure you check with your critique partners as well as people who aren't familiar with your work to see if your choice works. Ask yourself if making that choice really makes your writing stronger.
2.) Does it fit your character/setting/plot/story?
Think about the rule and how it will affect your characters/setting/plot/story. Does this rule honor those things or does is seem contradictory. If the rule seems to ruin an important aspect of your story you might consider ignoring that writing advice.
A good example of this is grammar in dialogue and thoughts. Not everyone speaks properly or is grammatically correct all the time. So there may be situations where you would ignore the rules of grammar. But again, going back to number one, make sure if you break the rules, you are doing it deliberately and you know why.
3.) Is it part of your voice?
Consider the advice, and then look at the voice of your work. Try editing a section using the advice. Did your voice disappear or diminish or did your work get stronger? If it got stronger then you should definitely follow that advice but if you lost the essence of your voice then you may want to consider ignoring the rule.
4.) Are you happy with your work?
Above everything else you have to be happy with what you've written. If you don't like it, you can't expect other people to like it either. So do what feels right. Write the best story you can and don't stress too much over all the rules. You aren't going to follow every rule all the time. It's not possible. But don't blindly break the rules either. Even if you still aren't sure whether or not you are the exception (and sorry but you're still probably not), at least you are aware of what you did. Make the conscious decision to ignore that rule, and know why you need to deviate from traditional advice.
Does anyone else struggle with whether or not to follow certain pieces of writing advice? Is there a time you ignored a rule or writing advice and your work was stronger for it?
