I guess for me it's always been, when I've like play acted. Been the "character" who has what he wants, and feel that way in real time. If I TRY to hold an image in my mind... it seems like too much work. I am a visual person but I prefer to write out short statements and just say them.
Guess I have my answer.
Here's a question though. In the Secret, Bob Proctor mentions debt. He says, "don't say you're out of debt, cause you're still thinking debt."
But saying I am debt free gets me all pumped up, even though it's "negative". I don't know how else to say it, without actually observing the thing I don't want.
