I've never read this book, so all I can do is suggest other places to read:
In writing an essay, be sure to follow the writing process:
1. Prewriting: brainstorm, research, plan, outline, thesis statement [This part of the process usually takes at least 25% of the time you spend on the whole assignment. If you don't plan well, if you don't have a really good thesis statement, you'll generally have problems with the paper.]
2. Writing: write your first draft by starting with section II of your outline; write introduction after the body of the paper is written; write the conclusion last.
3. Polishing: revise, concentrating first on the body of the paper, then the intro, then the concl (revision = making sure ideas are logical and sequential and support your thesis); proofread (spelling, grammar, usage, etc.)
Do you have a thesis yet? Have you done your brainstorming (and maybe research) yet? Have you written an outline?
