Yes, but an eternal truth, nonetheless. Also write from the gut. In other words, trust your instincts. The natural passion we writers have in common should not be suppressed, though it should be critiqued, edited and improved. If your writing goal was to attain perfection, think again.
Perfection is boring.
If your voice wants to break the rules, do it. Certainly, some of your wild ideas will have to go when it's time to turn your rough draft into a final, saleable manuscript, but not all. Your voice should live. Don't kill it by over-editing. And if you're part of a critique group, be respectful of your peers' voices.
