Man, My thoughts...Can not stop em

I've read enough succesful persons articles/bio's wherin they say, if you do not visualize it, you are hurting yourself and your mind.
I started doing this years ago and I would get swept away like I was in a Calgon bath. I thought of my whole life A.D. --->after deservedness.
Maybe I have ruined it.
I have been on 2 positive interiews for this awesome job and I am already living in Brooklyn or UpState NY where the train runs a block away from the job I did not get yet.
