Reality is going to absolutely rock your shit if you think that it just works that way. You will change as a person, you will age, and will die. Self improvement is finite. Eventually there will be a point that self improvement isn't enough. There may come a day where an unforeseen event happens and there's a new struggle. You won't be able to turn every frown upside down in life. Some of us clearly understand that better than others. It's okay if you don't have the fondest thing to say about the shit that you struggle with in life. Sometimes we want what's cathartic. Not everyone achieves that with thinking 'happy thoughts' of stuttering.
