Take notes. Jot it down. Then study it, absorb it, mull it around awhile. Okay, so what exactly is she talking about, you wonder. I'm speaking of style. When you hear the adage "read a lot, write a lot" you think that's great. You like to read and you like to write. So, that should solve everything. You will become the next Hemingway or be a bestselling author like Dan Brown. Right? Well, maybe you will. More than likely, instead of just reading you are studying. In that respect you really do get a lot out of the author's words, the style, the ability to make you feel what he or she has to say.
Some books on writing will advise you to copy down passage after passage of some work by an author you admire. That's a arduous and daunting task, but there are those who believe the ritual will help you absorb the way the author writes and make it yours. I tend to find a middle ground on this. I suggest whenever you see a word or a turn of a phrase that's clever, jot it down in a notebook so you can study it later. Or maybe it's a particular way a character acts, the words he or she says that catches your eye. Write it or describe it in your notebook.
I always think I'm going to remember what I've read or an idea I've had. I won't write it down and sure enough, it becomes buried, part of the tangled mass of thoughts crowding my mind. Write it down, please.
Then, when you have time to look over your notes, play with the words a bit. First, think and analyze the author's choice of words, the way he or she has put words together. We all want to avoid those overused, trite expressions like "clenching his teeth" or "squinting her eyes". When you see a unique phrasing, something that pops up from the page and you think, how great is that?, it's good to study it.
Next, try using some of those phrases, etc. in your own writing. See if it "fits" you. More than likely this exercise will help you to discover your own variation, a bit of an adjustment here, a little tweak there, and it's yours. Eventually--if you haven't already--you will find your own style. It will be drawn from all your experiences with reading and studying other authors' works. Then, someday, when you have your work published, aspiring authors will be studying you. And how awesome is that?!
Good luck in all you write :-)
