"It is one of the most saddening things in life that, try as we may, we can never be certain of making people happy, whereas we can almost always be certain of making them unhappy"

This quote by Thomas Huxley speaks with the problem of making people pleased. In spite of our best efforts, we can never ever be specific that our actions will bring pleasure to others. On the other hand, it is a lot easier to make people dissatisfied. We can inadvertently harm someone's sensations, or slip up that causes them distress. This quote acts as a suggestion to be conscious of our words and actions, as we can easily trigger pain to those around us. It also motivates us to be patient and understanding with others, as we can never ever be sure of the effect our words and actions will have. Eventually, this quote serves as a reminder that we should strive to be kind and thoughtful in our interactions with others.
