Its important to love ourselves, but also to practice humility.
Other people make mistakes, but we can make mistakes too.

Robert Burns in a poem wrote;

     Oh would that God the gift did give us
      To see ourselves as others see us.

 Mirror Mirror on the Wall I am the Bestest of them All.

I dreamt Death came the other night,
And Heaven's gates swung wide.
With kindly grace an Angel came
And ushered me inside.
And there to my astonishment
Stood folk Id known on earth
Some I had judged as quite unfit or of little worth
Indignant words rose to my lips,
But never were set free.
For every face showed stunned surprise,
No one expected me!
