towns. We lay out road networks. We create languages and number
systems. Interestingly, this very positive attribute can also limit our
potential when certain patterns become ingrained and we conse-
quently become resistant to change.

4 The brain loves to imitate

Allied to pattern making is the brain’s capacity for imitation. Until a
synaptic connection has been made there is no “knowledge,” except
what we are born with. The most efficient way for connections to be
established is by watching what others do and copying them. So, we
learn to speak and talk when we are young by watching and listening
to others. We learn many social customs by observation.
The capacity of the brain to mimic others is important.
“Sitting next to Nellie,” as it is sometimes called, is a great way to
learn. The use of role models and modeling certain behaviors at
home and at work are powerful methods of passing on learning. In
the workplace, coaches help to accelerate this process of intelligent
imitation. In most families, much of the learning takes the form of
copying other family members.

5 The brain does not perform well under too much
stress

Your brain has evolved from the bottom upward. The most primi-
tive functions are at the bottom of your brain, the brain stem. It is
here that rapid decisions of life and death are taken, those normally
referred to as “fight or flight.” If your reptilian brain and cerebellum
perceive a major threat to your survival, they have to act fast. In
practice, they trigger the release of chemicals like adrenaline and
noradrenaline (also known as epinephrine and norepinephrine),
which put your body into a state of heightened arousal. Either your
arms and legs begin to fight your attacker or your legs start to move
rapidly as you flee from the scene.
When your brain is under severe stress, it can only think of
survival. Blood and energy that would otherwise be available for
higher-order thinking in your mammalian and learning brains are
