That's what we're here for. This whole site is a place for you to try shit out. Anything. You wanna do the scene in a dress? Put it on. Wanna try a German accent? Nine problem. Wanna do it while jumping rope? Let's go Rocky.
You don't fail enough. Seriously. You need to fail a LOT to start to have the instincts about the stuff that's going to work and that's not going to work. You may try something and think, "Yeah! That's a great choice!" Only to find out it wasn't the best one that you could make.
You need to try at LEAST 10 different "ways" to do a scene before you can start narrowing things down about how you think it should be played. And by "ways" I mean anything from accents to being cold out to a whole other list of things that we'll get to with time. If you go in with your first choice, at best you're always going to come out of your reading wishing that you would've tried something else, at the worst, you're going to get an idea on the way home and obsess that "I should've done THAT!"
Since you're getting all the gold I'm putting out here, go ahead and be a failure today. Do the scene the worst way you possibly can. Make the glaring WRONG choice for the thing. You know what? You're going to find a little kernel of truth or insight by doing it that way.
