I was asked to do a post on instinct vs fear.
Here's a good commercial that explains extinct. Commercials usually explain getting girls better than schools.
What this commercial does is focus on a passive viewer's ego. The second tiger has the prey surrender to it, he succeeds in this fiction, so viewers invariably want to be the second tiger.
A smart viewer, however, sees that because there are two types of tiger, and not just one type, both methods must work. If first method did not work, it would simply be impossible for the first tiger to exist. Thank you, natural selection.
Both tigers operate on instinct in this case. And both tigers survive, even if we focus on any one tiger's failure at any moment in time.
If that little voice is telling you to approach her or even if it's telling you to not approach her, and you do anyway, that's instinct. If that little voice is telling you to approach or not approach, and you do not approach, that's fear.
Face your fears. And smile when doing it.
