I Don't Know. Here's How I Figure It Out.

When I'm facing something I've never encountered before, my first instinct isn't panic or hesitation. It's curiosity. "Oh, this will be fun." That mindset matters more than you'd think.

Build the model first

Here's what happens next. I don't start by memorizing what the error means or searching my brain for a precedent. Instead, I build a mental model of what should be happening: what the system would do if everything were working right. Then I compare that to what is happening. That gap is information.

The domain shifts, the approach doesn't

The specifics shift depending on what I'm troubleshooting. If it's a physical device like an actuator, I'm thinking about voltage, movement, basic inputs and outputs. If it's code or a system, I'm not focused on individual lines or syntax. I'm thinking about information flow: where data needs to go, what needs to see it, how pieces talk to each other. The model, not the mechanism.

Break it the same way

When I hit a wall, I often do something counterintuitive: I try to recreate the problem deliberately. I'll find a part that works, then systematically change things until I break it the same way. It sounds backwards, but it's actually cleaner than working backwards from a broken state. I'm not trying to understand the internals in isolation. I'm using the system itself as my teacher: watching it respond, learning from its behavior. Reverse engineering to understand how the pieces fit together.

You're building a library, not a list

When I finally figure it out, there's real satisfaction. But here's what matters: I don't consciously sit down and extract lessons afterward. The way I troubleshoot: iterative, observational, systems-focused, means I automatically absorb the patterns. I build a library of how products behave, not facts about them. And I carry that forward. I catch myself telling my team: "I don't know how this software handles it, but in this other software I've seen if you do X, Y happens. So I'd expect something similar here."

The whole thing

You're not memorizing. You're learning how to think about systems, recognize patterns across domains, and trust that if you understand the model, you can figure out the details.
