There are several ways you can read it, aren't there? One is "don't
think you're great just because you're good at one thing". Another is
"don't think you're useless just because there's one thing somebody else
is better at than you". Yet another is as an expression of the common
feeling of bewilderment one gets overhearing a conversation between
advanced practitioners of some field other than one's own.
