During a research experiment a marine
biologist placed a shark into a large holding tank and then released several
small bait fish into the tank. As you would
expect, the shark quickly swam around the tank, attacked and ate the smaller
fish.
The marine biologist
then inserted a strong piece of clear fiberglass into the tank, creating two
separate partitions. She then put the shark on one side of the fiberglass and a
new set of bait fish on the other.
Again, the
shark quickly attacked. This time, however, the shark slammed into the
fiberglass divider and bounced off. Undeterred, the shark kept repeating this
behaviour every few minutes to no avail. Meanwhile, the bait fish swam
around unharmed in the second partition. Eventually, about an hour into the experiment,
the shark gave up.
This
experiment was repeated several dozen times over the next few weeks. Each
time, the shark got less aggressive and made fewer attempts to attack the bait
fish, until eventually the shark got tired of hitting the fibreglass divider
and simply stopped attacking altogether.
The marine
biologist then removed the fibreglass divider, but the shark didn’t
attack. The shark was trained to believe a barrier existed between it and
the bait fish, so the bait fish swam wherever they wished, free from harm.
The Moral of the Story: Many of us,
after experiencing setbacks and failures, emotionally give up and stop trying.
Like the shark in the story, we believe that because we were unsuccessful in
the past, we will always be unsuccessful.
In other words,
we continue to see a barrier in our heads, even when no ‘real’ barrier exists
between where we are and where we want to go.
