It's not how good you are, it's how good you want to be.

That is the title of the book I just read by Paul Arden.  Some great stuff in it from the advertising guru.  Here is a passsage from the book.

“Header : It’s wrong to be right

Being right is based upon knowledge and experience and is often provable.
Knowledge comes from the past, so it’s safe.  It is also out of date.  It’s
the opposite of originality.  Experience is built from solutions to old
situations and problems.  The old situations are probably different from the
present ones, so that old solutions will have to be bent to fit new problems
(and possibly fit badly).  Also the likelihood is that, if you’ve got the
experience, you’ll probably use it.  THAT IS LAZY.  Experience is the
opposite of being creative.  If you can prove you’re right, you’re set in
concrete.  You cannot move with the time or with other people.  Being right
is also being boring.  Your mind is closed.  You are not open to new ideas.
You are rooted in your own rightness, which is arrogant,  Arrogance is a
valuable tool, but only if used very sparingly.  Worst of all, being right
has tone of morality about it.  To be anything else sounds weak or fallible,
and people who are right would hate to be thought fallible.  So: it’s wrong
to be right, because people who are right are rooted in the past,
rigid-mined, dull and smug.  There’s not talking to them”
