Regarding risk perception, I've always liked this quote from the book 'Adventures of a Dead Sea Smuggler' by Henry de Moinford:
"There was no use worrying about the possible difficulties to come, they always loom very large and terrible in the distance, but when one arrives at the foot of a wall there is always some foothold that enables one to climb it."
