The unknown.
Not knowing masks confidence. Questions interfere with exclamations.
The scariest part of the unknown is the dark blindness. There’s no GPS. There’s not even a path. It’s strictly aimless wandering.
Fear of the unknown can be defeated, but it requires a heaping scoop of one overpowering ingredient.
Curiosity.
The infinitely curious’s bravery goes unmatched in the face of darkness. Curiosity moves feet toward the darkness. Curiosity obtains the answers quicker.
