I'm worried on some subconscious level I'm sabotaging my career? What can I do about it?

If you think it's your subconscious that's causing your troubles, look in the mirror and talk to yourself, tell your self that you love your self and that your going to be great and that your going to be the person that you want to be, and tell yourself what qualities you want when your going to an interview. This has been known to work for many people.
