We've all been there: staring at a block of code, wondering what the original developer (or even past you) was thinking. That's where comments come in. Not just any comments, mind you, but the truly insightful ones. A good comment isn't just a restatement of the code; it explains the why. Why this particular workaround? Why this edge case? Why this seemingly arbitrary magic number? It's like leaving breadcrumbs for your future self, or for the next developer who inherits your masterpiece (or mess). So next time you're coding, take a moment. Ask yourself, "Will someone understand my intent here without me?" If the answer is no, a little comment goes a long, long way. Your future self will thank you.
