First, you need to stay on topic. This can make it appear that this subject is the most important one in your life. We're pretty complex beings and, while one part of your life may have affected you profoundly, it isn't necessarily your main focus or something that you think about every day.
Second, you have to dish out your information in tiny little bits. Nobody wants to read a long blog post, so you need to decide every day what little teaspoon of your story you want to share and hope that the reader won't get bored before they get to the good stuff (the stuff that they want to hear about).
