The moment I began the tour this morning, I knew that I was under-performing. It was one of my worst sessions in all these years. The hoo-ahness wasn’t there, and it never came. I didn’t even bother trying hard. It’s just not been a good day… distractions, thoughts, dread in my mind, and I was tired from the week. Never underestimate the importance of the state of mind of a nature guide in effective nature interpretation. I felt sorry for my visitors.
