How do I break down a big messy problem?

A tangled problem lands in front of you and your mind just freezes. It is too big, too shapeless, and you cannot find the thread to pull. That paralysis is normal. A mess resists being solved precisely because it has no edges yet, and your first job is to give it some. You do not break a problem down by being clever. You do it by asking simple questions and writing the answers where you can see them. What am I actually trying to solve? What are the few big pieces of it? A problem you can see on a page is far less frightening than one swirling in your head. So take your messy problem and split it into no more than three or four parts, even rough ones. Then pick the single part you could make progress on today and start only there. Structure is not a gift some people are born with. It is what happens when you refuse to hold the whole thing at once.
