When I have nothing to shoot, I do rigorous lens/lighting/quality testing. I'm also learning more and more about blocking. I usually just place random objects and think of them as characters and just plan how to shoot them. It gets a little tricky when you're up to more than 10 characters that all have dialogue and are scattered throughout the room/set. You don't have to go out and shoot to master your craft ( well you do, but not always ). There's always plenty of testing to be done and plenty of new techniques to be learned. I'm sure to some of you hypothetically owning an Epic would automatically result in great footage, and that's not the case.
