It's not so much "difficult" as it is "finicky."  There's lots of
little details to attend to that aren't really written down anywhere.
A bit like writing.  not trivial, but most people can make themselves
understood, and only a few write best-sellers.

The trace width thing is really common; narrow traces make for easy
routing, and it's the eagle default.  You happened to have a circuit
that really deserved big traces to handle the current, but in many
cases the board will work fine.  I like to design boards I can make
at home and have them be robust, so if I can make ALL my traces 1mm
wide, I'm a happy camper...

(and I keep going back to boards I thought I was done with and
saying "gee, that was silly...")
