In James A. Michener's book "World Is My Home," he reflects on the impact of urban life on his well-being. He conveys a sense of illness he associates with being disconnected from nature, a condition he describes as nesomania. This feeling underscores the importance of a close relationship with the natural environment, which can often feel lost in the hustle of big cities.

Michener emphasizes that life on islands allows for a deeper engagement with the cosmos and natural elements. In those tranquil settings, there is both the time and motivation to form connections with the stars, trees, and ocean, leading to a more profound, intense way of living. His insights highlight the need for harmony with nature to foster one's mental and emotional health.
