Here is a great, general response (not written by me), which, not surprisingly comes from Seth Godin's blog about The Dip:
The one possible weakness of this otherwise terrific little volume
is that it is aimed solely at people who are creative, intelligent and
want to succeed. Those who are mediocre, unmotivated or just coasting
through life will probably not get much from Godin. He is not an
elitist, but his message is squarely aimed at those who want to succeed
or at least achieve excellence.
