Go buy a piece of fruit you haven't had in a while: a peach, a plum, a pear, a mango, even a carambola (starfruit, though they're not as good here on the mainland as they are in the islands.) Find a place to sit alone and close your eyes. Try to imagine you're a primitive human. Game is scarce, you've been living on insects and grubs, or bland roots. You're always on the verge of starvation, though never quite starved - a terrible state if you've ever lived through it.
You see this thing hanging from a tree. You've never considered eating it before because, well, it's on a tree. What part of a tree ever tasted good? Wood, bark, leaves... Still, finally hungry enough, you climb up, pull this thing down, you bite into it (bite into the fruit you bought now.) Try to experience what that starving primitive experienced as glorious sweetness and a flavor you've never imagined could ever exist floods your mouth and your soul soars.
Many times I read work from writers who, in their jaded experience, seem to have forgotten that not all of their readers have read the same old tropes and traditions a thousand times. They sometimes neglect details that could enrich their story. How many times has a gun been fired in a thriller or mystery? So many times it is just accepted that readers know what it means to fire a gun, or have one fired at you. So why describe the way your nerves jolt at the sudden blast, the sound waves stinging your skin like electricity, the smell of expended gunpowder, the intense silence following the explosion, the heat you feel from the bullet as it leaves the barrel...or as it tears into your flesh?
Never forget some of your readers may be reading your genre for the first time, and you are their sponsor. Even if not, being reminded of details that often get glossed over or skipped because they are rote or common, can electrify some long-steeped and jaded readers, too. As you write such things, take a moment and close your eyes, try to experience the thing as your character would experience it (whatever it is, whether firing a gun, stealing a candy bar from a store, having sex). Is it their first time or they are old pros? How would that affect the experience.
Never let such things become rote or old hat in your stories. Always remember while you may have written/read similar scenes a million times, your character has not, and your reader is identifying with them. Always keep it fresh, as if this is the first time anyone ever wrote a scene like this. Never let the jade show under your skin.
