The real trick here isn't merely swapping dread for optimism—it's recognizing that both emotions are powered by *imagination*, so you might as well imagine productively. Most people assume fear is the honest response to uncertainty, when actually both fear and excitement are equally speculative; you're simply choosing which story about the future gets your mental energy. When you're preparing for a presentation and your stomach flutters, you can interpret those nerves as either "I'll humiliate myself" or "I'm about to share something worthwhile"—the physiology is identical, but the narrative you attach determines whether you show up timid or engaged. That shift in framing isn't positive thinking; it's honest thinking.
