In the conclusions chapter of my book (technical, non fiction writing) I want to go over the main ideas I addressed throughout the entire book, as a reminder for the reader and really drive in some of the concepts. One approach would be a bulleted list, but I don't really like it since I don't have any other list in the entire book as I managed to avoid them by choosing a different wording. However, in the last chapter I find it difficult to have the ideas expressed as a narrative because they are not related to one topic/chapter, but all of the topics/chapters.
I've worked a draft of the final chapter, but many of the paragraphs start with "I mentioned about...", "I said...", "I stated that...", etc. I find this very repetitive and annoying. But I don't know how to tie in one paragraph after another when the ideas are separate items.
Are there any techniques for writing a list of conclusion items as paragraphs, without repeating wording like those above?
