Two minds under the same roof
Murphy starts from a simple division: a conscious mind, which chooses and decides, and a subconscious mind, which records whatever the conscious mind accepts as true and works underneath, nonstop. The comparison he uses is the driver and the engine: the conscious mind steers, but the force that moves the car comes from the engine, hidden under the hood.
The problem, according to the author, is that most people look after only the conscious mind, what they'll say in a meeting, what they'll post in the neighborhood group, and ignore the engine. Then they wonder why they work hard and get nowhere, without noticing that they keep telling the subconscious things like "I have no luck" or "this month won't add up."
For Murphy, the subconscious doesn't debate, it only executes. If the conscious mind sends, with repeated conviction, the message "I'm the kind of person who misses the bus and shows up late," the subconscious arranges the day so that it happens again, not out of malice, but because that's the instruction it has received most often.
