Writing a Discussion Chapter

Last time, I thought that writing the literature review chapter was the hardest task. Now, I think the hardest part of thesis writing is writing the Discussion Chapter. This is the part that I have to be extra careful so that:

• I have the facts that I found right,
• I have my commments to the facts right, and
• I have outlined the theoretical implications of the facts right.

Indeed, this chapter requires very careful thought. But, the question is: How to use my original argument and call on my results in oredr to make the whole meaning of your findings absolutely clear?
