Very insightful point. Your current state depends on your previous state. You don't go through life unfazed. Every experience turns you into what you are the next day, which results in repeated transformations. A small change in your life then, e.g (deciding not to go to a Spanish-speaking country) would result in many changes, including your comment not existing, and me never having written this comment. Then it's funny to consider the chances that I would have gone on to make a life-changing decision because of this thread.

Pretty interesting stuff.
