Don't be afraid to succeed. People with low self-esteem are often afraid to succeed because they feel they don't deserve success.
I was scared this year. I found comfort in self-sabotage, like let me trip myself before somthing else trips me... I found that utter failure was much more comfortable a concept for me to deal with than possible success. Failure matched the image I had of myself.
If only I knew what I was doing - evading issues, side-stepping... doing anything to avoid being me, cause the idea that I could deserve to be happy scared the shit out of me.
It's like Nelson Mandela said: (paraphrased) we're not afraid of failure, we're afraid of being successful. My greatest obstacle, perhaps, my only obstacle will always be my self-doubt and shame.
