I only occasionally achieve this state but I find that it comes from high levels of comfort with the systems you're using. That's everything from the operating system to the programming language to your chosen editor/IDE.

When you have a high level of comfort with all of these things when you see a problem you can often guess *where* the bug is and that's half the battle right there.

Have you ever noticed that your friends will ask you to fix their WiFi or an app on their phone and even though you have no real expertise you can normally do it? That's a version of the same thing. You understand the general principles of the system and you're able to guess the general location of the problem and start flipping switches until it goes away.
