Your reticular activating system is like a filter between your
conscious mind and your subconscious mind. It takes instructions from your
conscious mind and passes them on to your subconscious. For example, the
instruction might be, "listen out for anyone saying my name".
...you can deliberately program the reticular activating system by
choosing the exact messages you send from your consicous mind. For example, you
can set goals, or say affirmations, or visualize your goals.
I know they say to set realistic goals, but I figure it doesn't hurt to write down things that might seem wildly implausible. I notice in my own I-Can-Do-It Can from years ago that I had drawn and written that I wanted to own a house. That seemed impossible due to financial circumstances at the time, but it's happened!
