Adventure itself is defined by the unknown elements of life. It always involves some headlong plunge into unpredictability, into the unknown. And if adventure were predictable and quantifiable, then well we wouldn't call it adventure. We'd just call it algebra or something. Experts can have a hard time with adventure, wanting things figured, anticipated, and calculated. An expert is a nice thing to have around when expertise is needed, but most times the fun is in overcoming the challenge of not knowing. The need to be an expert often inherently sucks the fun out like a leech sucking blood from its host.
