How do philosophers stretch an idea to write an ENTIRE book?

  I have a few philosophical thoughts that I wish to put into a book.  It is, essentially, about how to think.  Certain ideologies have almost plagued minds and people have forgotten how to do simple logic.  This book will explain what is a valid argument, who has the burden of proof, etc.  There remains a problem, however.  The ideas I wish to show could be explained in ten or so pages.  I'm wondering how philosophers manage to "stretch," so to speak, their ideas to make up an entire book without it becoming boring and redundant.  Could you please give me some tips on how to do such a thing?  In advance, thank you for your answers.

It seems like you're not taking into consideration a couple of things.  

The first is that philosophical problems are really complicated -- there's no way you can explain your view on those topics in ten pages and have anyone take it seriously because it would have to be so superficial.  It's not that philosophers who write books stretch an idea; rather, its that what you think is the idea is only the first layer of a vastly complicated structure. 

Second, in order to be taken seriously, one has to engage with the literature on the topic--say how your view fits into the gigantic conversation that has been happening for the last several thousand years, which includes dealing with obvious objections, explaining why your view is superior to others, etc. On validity alone there are thousands of pages written each year. In sum, if you don't know what to say about your topic beyond a dozen pages, then go read what others have said about it.  You'll soon figure out how complicated it is and how to flesh it out by engaging with existing ideas.
