It all depends on, who and how, the critique is delivered. You must consider critiscism very closely from pople who know you well. I'm sure many of us are self critical in the first place ! I liked Mo the Callers scenario whereby the Caller seems to have dealt with the matter in a contructive manner . When you have no control over the critique it could end up like this, which is a most unstaistfactory way of dealing with criticism: -

HE COULDN'T SING, HE COULDN'T CLOWN,
NO, - HIS ART IT WAS IN PUTTING PEOPLE DOWN,
HE COULDN'T PLAY, BUT HE COULD WRITE,
AND WITH HIS PEN HE WENT AND BROKE A HEART LAST NIGHT.

                                     2.
HE SITS ALONE, WITH BLINKERED VIEW,
DOESN'T KNOW THE HOURS OF PRACTISE PEOPLE DO,
TO PLAY THE SONGS, - TO GET 'EM RIGHT,
HE SIMPLY TOOK HIS PEN AND BROKE A HEART LAST NIGHT.

CHORUS / REFRAIN                                                                                    
                                       
WELL IT'S A MYSTERY TO ME., - HOW THE CRITIC" FORMED" YOUR MEMORY,
NOW ARE YOU TELLING ME, YOUR EYES AND EARS DECIEVED YOU!!

                                        3.
HE NEVER HEARD THE CROWDS' APPLAUSE,
AND AS THEY MADE THEIR EXIT THROUGH THE THEATRE DOORS,

HE NEVER SHARED THEIR WILD DELIGHT,
INSTEAD, HE TOOK A PEN AND BROKE A HEART LAST NIGHT.

                                        4.
TO READ HIS WORDS - THEY MADE NO SENSE,
THEY NEVER MATCHED OUR RECOLLECTION OF EVENTS,
ONLY FOOLS BELIEVE, WHAT BIGGER FOOLS WRITE!      

TAKE CARE THE CRITIC'S BREAKING HEARTS AGAIN TONIGHT.,   

(Almost repeat of the previous 2 lines :-)
ONLY FOOLS BELIEVE, WHAT BIGGER FOOLS WRITE!

TAKE CARE THE CRITIC'S CHANGING MINDS AGAIN TONIGHT.
