Adding one more thing to my comment -- I think an important skill is the ability to put details in boxes and then kind of forget about them. Eg when thinking about a software system, being able to look at it with the appropriate "zoom level." The shape of the boxes, and how they relate to each other, are what you need to look at. Crucially, though, this doesn't mean details aren't important, it means they're not important _right now_. That's why I picked the analogy of the boxes; you will at some point need to open up the boxes again.

Or another way to try and explain it -- you can't keep everything in your mind's "RAM" -- when trying to think systematically, you need to offload the details onto disk for later retrieval. Don't throw them away! People who are "vision people" and brag about not sweating the details become really annoying to work with as a software engineer -- but you won't be able to grasp the system if your mental RAM is cluttered up with those details all the time.
