What are some hard facts about life? I mean the no-doubt-about-it, irrefutable truths that you know for sure are definitely true about life. Make a list of them. Next to each item on your list, jot down reasons why you know these rules are true.
How many items on the list are indeed hard facts (we’re all born, we’re all going to die eventually…) and how many are things you believe are true but may not, in fact, be universally true? Note that, too, and take a moment to consider why you believe they are true, anyway. See where that leads you and dig in to write about that.
