Tried and true method to design; any type of design. This will help you to avoid the "blank paper" syndrome.
(1) Think. Think a lot. Develop the idea with thought and exploration. This is when the idea is in its most abstract form. Take advantage of that by exploring many areas of the idea.
(2) Pen and Paper. This is somewhat of a misnomer, because you can use a digital notepad, or something similar, but the idea here is that you're working in a space that is *not the production environment* (in this case, not the Hubpages interface). I actually prefer a real pen and real paper.
(3) Once steps (1) and (2) are complete, review all the information you have and start collecting resources. Do you need to take pictures, shoot video, find statistics, cite any other works, or perform an interview? Make sure you have your external resources in place.
(4) Outline your hub. I typically do this in a note pad on the computer and have it up next to the screen when I'm writing. Your sketches will most likely be a little scattered and disorganized. In this step make sure your article flows nicely, makes sense, and is achieving its goal in its strongest form. This means deleting the weak elements of your idea and arranging the keeper ideas in the best way possible.
(5) Write your article.
(6) Read and Re-Write your article. This is the editing process. Do not be afraid to delete sections or completely re-write them. Good writing is rewriting.
(7) Hit publish, and start spreading the word.
