My take on this, or in my case I came to the conclusion that my fear of success is directly related to this: I was eight years old doing my thing living and loving life when my parents divorced, ripped my world apart, nine when I was molested, ripped my world apart. I was successful up until my life was ripped apart after that I no longer wanted the success because of the fear that someone or something would come and rip my life apart. It was better for me to have things that could be lost without great pain therefore I did not try to achieve or have things of great value to me. My fear was the loss would be to much for me to handle. I set myself up to have nothing of value to lose and it did not work. My healthy side wanted nice things, felt that I deserved it but the unhealthy side would not let it come about. I wrote about this in the book some time ago but it feels like yesterday the way its coming back to me now.
Hope this helps,
