Stephen,
What Ken is talking about are "triggers".
He's attached his own "personal" idea/value to each image/trigger he's just mentioned.
The idea behind this, is when you see each of these visual triggers, you're reminding your subconscious mind about your desires--both short term and long term.
In addition to the "visualization" subconscious work others recommend: i.e. the theater in your mind, the law of attraction, etc., what Dan Kennedy(and I'm sure others) suggest is surrounding yourself with "triggers" that remind you of wealth... whatever your definition is.
Dan Kennedy talks about having foreign money on his walls... lots of clocks in his home office... and a kitchen drawer full of: because he uses spoons the most in his house. Hence when he opens the drawer for a spoon, he always sees money.
And he also talks about carrying and spending cash as opposed to credit cards for everything, though he admits to using credit cards.
I have, hanging next to my desk, my goal board:
my dream home that I got the blue prints from eplans.com...
my dream client list (which has recently been fulfilled in the last 3 weeks

...
the EXACT amount of money I desire to earn per year... and in the next 10 years... my investing goals...
my 6 year-old son's personal development curriculum (full of tennis which he's darn good at for being 6, math, and his violin lessons)...
and a picture of me, when I was 17. It reminds me of personal freedom (very important to me), creativity, fearlessness, and most of all health.
Great post Ken. Not only to remind, but to help others with the concept of psychological image triggers in your workspace/home.
