Fear can be a deciding factor in whether or not we do something.
It can overwhelm a person, making it impossible to act. Or it can be a motivating factor.
While fear itself will not drive discovery, it can cause a person to be more apt to act in some situations.
When fear arises, listen to it. What is it warning you away from? It may be that what scares you is the thing you need most to head towards.
