“Beware of Big Doubt the most,” The Professor said. “There will be times when you get your ass kicked so badly from The Travels that you will stop believing Reality Travel is even real anymore. I told you the first day how badly it would kick your ass, and how if you weren’t 100% willing to accept all the sacrifices of your Calling then you should leave The Training. But no one ever listens. They are too excited and think it won’t be hard for them, but as soon as they see how powerful The MeNotzies are, how hard The BoobyTraps are, how no one is grateful for the vitally important service you’re doing for The World, and how all those Realities who’ve never even heard of Reality Travel seem to be living such peaceful, prosperous, ass-protected lives, they just can’t take it. Big Doubt can happen to any Reality Traveler, and it is the hardest BoobyTrap to escape. Fellow Reality Travelers, including me, will not be able to convince you. You summon your Guardian Angel for assistance during moments of Little Doubt, but once you’re in full blown Big Doubt they’ll only seem like a figment of your imagination. This is when a Traveler must Dig Down Deep, find a reason to believe, and try to save themselves.
