In the novel "Lonesome Dove" by Larry McMurtry, the character reflects on his past actions, acknowledging that he engaged in many reckless and foolish behaviors. He did this in an attempt to validate his self-worth and to counter feelings of inadequacy. These actions were driven by a deep-seated need to prove that he mattered and could achieve something meaningful.

This exploration of his past highlights the universal struggle with self-worth. Many people seek external validation through their choices and actions, sometimes leading to poor decisions. The quote captures the poignant realization that striving for validation can often result in a cycle of reckless behavior, a theme that resonates throughout the narrative.
