The quote from Larry McMurtry's "Lonesome Dove," advises against harsh self-judgment. It highlights the idea that individuals are often their own worst critics, making it important to recognize that we may not be the best judges of our actions and decisions. This perspective encourages self-compassion and understanding, suggesting that we should be more forgiving of ourselves instead of dwelling on perceived failures.

Furthermore, the message implies that everyone struggles with uncertainty and doubt when making choices. By reminding us that we all share this common experience, McMurtry calls for a more empathetic view towards ourselves and others. Ultimately, the quote serves as a reminder to approach life with kindness, both inwardly and outwardly, acknowledging that we are all human and imperfect.
