Geez, that sounds pretty ambitious. I would've thought five seconds might be a good level to start at, and work up from there. What usually comes up for me when I try exercises like that (or affirmations, for that matter) is all the reasons why it's not so for me, and can't be, and mustn't be, and I don't want it to be. Then, when the smoke clears (which usually takes a while) I may start catching glimpses of the possibility that it might be so after all, or that I might have some choice in the matter...
