Samwise Gamgee in J.R.R. Tolkien’s The Lord of the Rings, specifically when the Ring tempts him with visions of power, offering to make him a great gardener-king over Mordor. Sam resists by recognizing his true desire: a simple life in a small garden, showing his humble, hobbit-sense and contentment, a key theme in Tolkien’s work about ordinary folk keeping darkness at bay:

He knew in the core of his heart that he was not large enough to bear such a burden, even if such visions were not a mere cheat to betray him. The one small garden of a free gardener was all his need and due, not a garden swollen to a realm; his own hands to use, not the hands of others to command.

A heart of gratitude is the key to lasting happiness.
