A gist of few books I read:
You are run throughout your life by your subconscious mind but amazing fact of psychology is that, your subconscious can't think, it only runs you on the beliefs you have fed it through your conscious mind. The only cure for your negative thoughts is by verbal positive commands. Do not use negative commands in your positive commands. Let's say if you are scared of a dogs, do not say that I am scared of dog rather say I love dogs. Fact being your subconscious does not accept negative commands without positive experience. Let's say a child is hanging from a branch of a tree and you say don't fall, if that child has not experienced any fall from such a height he will fall. Reason, subconscious mind will first experience the fall then it will create a positive belief that falling hurts.
