This
quote is scientifically proven to be true! 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 to 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.

However, the
second time you walk through, it won't be as hard because you
already started creating a pathway through the jungle on your
first walk. Now, every time you walk through, you make the pathway
larger and so there is less and less resistance to your walk.
Eventually, the pathway will become a track, , then a small
road and ultimately a large road!

It's the same with your brain.
Every time you think a thought, the resistance is reduced
therefore increasing the likelihood of you having that thought
again. This is how habits are formed. And it is why it is vitally
important that you monitor your thinking. If you think negatively,
you will build a strong connection of negative thoughts so you
will be more likely to keep repeating those negative thoughts. Try
to ensure that you are creating positive thoughts and good
habits.
It also explains why learning
something new or breaking a habit can be difficult at first. The
key is to stick at it and it will become easier. It's often not
enough to simply stop doing a certain habit. You must replace it
with a new habit and focus on creating this new good habit as your
new way of thinking.
