The quote "Never test another man by your own weakness" from Joseph Conrad's "Lord Jim" emphasizes the danger of projecting one's insecurities onto others. It serves as a reminder that we should not judge others based on our limitations or flaws, as this can lead to unfair assessments and strained relationships. Each person has their own strengths and weaknesses, and recognizing this individuality is essential for understanding and compassion.

This concept encourages self-reflection and personal growth. Instead of criticizing others for traits we may struggle with ourselves, we should focus on fostering our strengths and supporting others in their journey. This wisdom suggests that true empathy comes from understanding others in their own context, rather than through the lens of our shortcomings.
