With regards to the subject of visualisation and the suchlike, there is no such thing as a 'negative affirmation'.
So when you think "no jack, no jack, no jack!", the message you're really sending out into the universe is: "jack, jack, jack!"
This is why it's better to say to a child:
"Be careful carrying that plate".
As opposed to:
"Don't drop that plate".
The former is a positive affirmation. The latter is a negative affirmation, which doesn't exist, so it becomes '
drop that plate'.
Now, whilst utilising the metaphysical machine (that is our universe) is unlikely to do you any more harm than worshipping another diety, I would also suggest focusing on the aspects which are within your control.
Making good, +EV decisions, studying and analysing will serve you far better than trying to sway the Poker God's or universe's affections... :wink:
