Another principle that McCandless embodies is the idea of self-trust. He is confident in his ability to live off the land and survive in the wilderness, despite lacking formal training or experience. He is also willing to take risks and make difficult decisions, such as abandoning his car and burning his money, in pursuit of his ideals.

McCandless also demonstrates the principle of simplicity. He lives a minimalist lifestyle, carrying only the bare essentials and rejecting material possessions. This allows him to focus on his own spiritual and philosophical development, rather than being distracted by consumerism and materialism.

Finally, McCandless embodies the principle of individualism. He rejects the notion that he must conform to societal expectations and instead follows his own path, guided by his own values and beliefs. This ultimately leads him to a tragic end, but it also inspires others to embrace their own individuality and pursue their own dreams.
