Henry James, in his book "Roderick Hudson," explores the concept of true happiness, suggesting that it emerges from selflessness and engagement with the world. He asserts that simply stepping outside of oneself is insufficient; one must also remain engaged in meaningful activities. This idea emphasizes the importance of finding purpose in life.

James further posits that to maintain this state of happiness, individuals must be occupied with a compelling mission or pursuit. It highlights the idea that contentment comes from being dedicated to something larger than oneself, reflecting a deeper understanding of fulfillment and joy in life.
