I start at the bottom and work up.
Find the error, then look back to find why that error occurred.

Experience helps, but I admit the volume of debugs does look
daunting to begin with. But it's pretty much all relevant. Which
is why most questions to this list without debug output result in
"provide the debug output", and few questions that include the
debug output result in requests for further information.
Network RADIUS provide a debug highlighter if that's your thing.
