The happiness of most people is not ruined by great catastrophes or fatal errors, but by the repetition of slowly destructive little things.

Summary

This quote suggests that people's happiness is not typically destroyed by major disasters or significant mistakes, but rather by the accumulation of small negative actions or choices over time. These little things may seem insignificant individually, but their constant presence can have a slowly undermining effect on one's overall well-being and contentment. It serves as a reminder to pay attention to the smaller aspects of life and make conscious efforts to avoid negative patterns that can gradually erode happiness.
