Fanfiction Failure Metarule #6 -- Do what they tell you not to or shouldn't. Who are 'they'? They are the know-it-alls of fanfiction; even other authors. This particular rule is a close cousin to metarule #3 and has served me well over the years. They tell you not to put specific dates in your fic? Do it. They tell you that writing about X will only cause problems. Go for it. Not only will you set your work apart from theirs as unique, your readers will appreciate you tackling subject matter others are afraid to touch. Trusted prereader advice should always take precedence over this rule, but always keep it in the back of your mind. Asking yourself 'why' somebody advises against certain material is half the battle whether you take their advise or not.
