Give me a simple diagram and I'm fine. But someone unrolls a full set of schematics, page after page of lines and symbols and callouts, and my eyes just slide right off. I flip between sheets pretending to follow while the crew waits for me to say where things go.
More people experience this than they realize.
You can read simple diagrams but complex schematics still confuse you.
If this sounds familiar, the Library can help you find the bigger picture.
