The neural pathways discussed earlier in the tour, create patterns of thought. Once these pathways are created, the thoughts are likely to be repeated. This is because, the repetition of a thought decreases the biochemical resistance to that thought happening again and the connections between two brain cells on the neural pathway become stronger. Imagine that you are taking a walk through a dense forest. The first time you go through the forest, there is much resistance to your passage through so you have to use your machete to fight your way through.
