The wise man thinks without speaking; the fool speaks without thinking

 This proverb is a classic example of the contrast between wisdom and foolishness, emphasizing the importance of thinking before speaking. The wise man thinks without speaking: This reflects the ability of a wise person to think deeply, analyze situations, and weigh the consequences before expressing an opinion. This is a sign of self-control and maturity, where words are used thoughtfully and purposefully. Silence in this context is not a sign of ignorance, but of inner strength and observation. The fool speaks without thinking: This describes the impulsiveness and lack of thought that often lead to thoughtless statements and actions. The fool is often guided by emotions and momentary moods without considering the impact of his words on others. This can lead to conflicts, misunderstandings, and loss of trust. The proverb creates a stark contrast between two opposing ways of behaving. This contrast serves as a warning about the dangers of thoughtless speech and as a praise for wisdom and self-control. The proverb also teaches us that sometimes it is better to remain silent than to say something we will later regret. The proverb "A wise man thinks without speaking, a fool speaks without thinking" is a timeless advice about the importance of reflection and self-control. It reminds us that words have power and that it is important to use them responsibly. 
In general, politicians suffer the most from this proverb. And we people suffer the most when we say something related to people we love or are surrounded by. Then we look for an excuse that everyone around us is toxic and bothers us. And we never look for our problems within ourselves.
