In James A. Michener's book "Caravans," the statement "We are never prepared for what we expect" highlights a central theme of the narrative. The characters embark on a journey filled with uncertainty and unforeseen challenges, illustrating that anticipation often falls short of reality. This notion resonates deeply as it reflects the complexities of human experiences and the unpredictability of life.

Through the characters' encounters, Michener emphasizes that despite our best efforts to plan and prepare for what lies ahead, we often find ourselves caught off guard by life's surprises. The theme serves as a reminder that embracing uncertainty can lead to personal growth and discovery, making the journey itself as significant as the destination.
