Pull your mind into focus and set your priorities. This will give you a sense of direction. As you move through the next few weeks, you're likely to revise your plans many times, or more likely, rework the language you use to describe them. I suggest that you not get lost in the sauce of thinking that the words you pick to describe something are more important than whatever they are designed to illustrate. Focus on your central idea and you'll find it a lot easier to be clear. Stay close to your subject matter. At the same time, keep shifting your viewpoint, so you get a more full panorama. Notice when your perspective gets stuck. When it does, move around and look from another angle, or through a different lens. If you find yourself arguing, argue the other side of the case as well, and then weight and balance what you learn. Language is always a matter of experimentation, of revision, and of getting the best approximate fit between a concept and how you sketch it out. Think in terms of improvement rather than perfection. Remember that good writing is not merely about clear words but rather about expressing clear ideas. And it can take some time to get there. If you consider that you're describing something that already exists, this process will be much easier.
