Material for the third and final part of this book (tent. ent.: personal mythologies) are best kept short and somewhat anecdotal, exploring how the ideas in your life have affected the events of your life. Tone counts for a lot here, moreso than an academic essay. Shoot for 750-2500 words.
Beyond that it is hard to detail the contents of what will "work" for this kind of essay, as all our experiences differ. I'll know it when I see it, and you'll probably feel it as you're writing it.
