I don't actually know how much this post will help you in ridding your works of pesky anachronisms, but the title just seemed to clever to resist. If you're not already familiar, an anachronism is a literary, spatial or temporal (usually temporal) transplant. A detail, a phrase, an expression, a device, or really anything else could be an anachronism; most commonly these are stock expressions or devices of our own time that we accidentally put into our works. Nor are they unique to literature, as there are plenty of examples in movies and other media. For instance, perhaps a period movie might show cars from a later model year driving around in the background. Or my personal favorite, when an author or screenwriter has archers "fire" their arrows, an expression which could not predate the advent of firearms. This last one even made its way into The Lord of the Rings movies (notably during the battle at Helm's Deep).
It's almost considered too blunt to say that someone died. Instead, we might say that they passed away, or that they passed on, or that they lost or gave their lives. Some might argue that the difference between those wordings is slight, incidental, even meaningless. After all, in cold facts the end result is the same. Yet those words are different, they mean different things, and we use one or the other to convey different meanings - this is especially true of the last two examples. The difference between losing a life and giving a life may be subtle, and yet it makes such a difference in how the person and the event is perceived. One makes the death a tragedy. The other makes it heroic, because it expresses that there was a choice involved, it gives the individual agency.
Criticism is a vital part of literature, and for that matter most fields. Active, reasoned critiques help identify weaknesses and strengths, provide multiple interpretations and perspectives on disparate matters, and foster improvement, perhaps more than anything else. They are just as essential to individuals; critical feedback is immensely helpful to improving oneself in any number of aspects, whether that's a specific ability, or more generally. It is something that we are encouraged to actively seek out in order to understand how our work and how we are perceived and received by others. Unfortunately, it is also something that I struggle with receiving.
Over the past few months, I've been slowly making my way through the extensive historical archives of the Peanuts comic strip, starting all the way back at its inception in 1950. I don't usually get a lot out of comics, graphic novels, and other, similar forms - my patience and interpretive abilities for these visual media are only somewhat higher than my abilities to create in such media - but Peanuts was enough a part of my childhood that I am enjoying reading through them all from beginning to end. This rather esoteric project began from a random curiosity about how the strip originated, and while I continued with it in part because I was enjoying them, and out of curiosity, it also became something of a writing exercise.
Creative writing, or the speculative fiction genre, has long leveraged something called the MICE quotient. I first came across this when I was reading an Orson Scott Card book on how to write science fiction and fantasy (I think it was even titled How to Write Science Fiction and Fantasy). The premise is that stories in the speculative fiction genre can be broadly binned as having one or more of four, primary drivers: milieu, idea, character, and event. Although most good stories will incorporate multiple of these components, with different ones emphasized at different times, there is usually one that drives the story forward.
