If someone shows me the broken line, I can fix it no problem. But when something fails and I don't know why, I just stare at the screen with no idea where to even begin. I click around randomly, hoping I'll stumble onto it, feeling more lost with every minute.
More people experience this than they realize.
You can fix a bug you're shown, but a failure you don't understand leaves you with no place to start.
If this sounds familiar, the Library can help you find the bigger picture.
