I am convinced, this is no matter of self-centered behavior or feeding yourself with self-pity. As I wrote before, It takes courage to look at yourself (really dare to look at yourself and reflect) and even more courage to work on it. Self-knowledge is the beginning of all wisdom...
To be honest, I often think:  I didn't want myself, but I accept myself! 
To me, this is not a pessimistic or dark thought, but really accepting myself as I am. With all my flaws and qualities.  
And even more, when we're aware of our shortcomings, it's a powerfull tool to convert it into qualities.
