Chronological sequence is best suited if your topic is a narration of events, describing a process, or giving directions or instructions. Flashback order, which is similar to the chronological sequence, is used when giving anecdotes, or personal experiences and examples. Reflective structure on the other hand, is combined with a list of your opinions about the topic. You can choose from any of these structures, but it is not uncommon for people to combine these structures. Just make sure that you the logical flow is clear and consistent all throughout the essay.
Another important thing to remember when constructing your personal essay outline is the conclusion. For this, you must reemphasize your thesis and main points, and achieve a sense of closure with your reader. Usually, quotes and anecdotes are used to end essays.
