Wisdom lies in the ability to prevent clashes and find common ground. Here are 10 rules that can help with this:

1. **Respect the feelings and opinions of the other person**
Each of us is unique, and each of us has his own view of the world. Recognizing this and respecting differences is the first step to preventing conflict.

2. **Listen more than you talk**
Sometimes, in order to understand the situation and find a compromise, you just need to listen. Listening helps to better understand the reasons and motivations of the other person.

3. **Avoid accusations and criticism**
When we criticize, we provoke a defensive reaction. It is better to focus on solving the problem, rather than finding someone to blame.

4. **Take a break**
If you feel that emotions are heating up, take a break. This will give you a chance to cool down and think about your words and actions.

5. **Avoid sarcasm and causticity**
Sarcasm rarely helps to resolve a conflict; on the contrary, it aggravates the situation. It is better to use a friendly tone.

6. **Focus on the problem, not the person**
Avoid personal attacks. Discuss a specific problem or situation, not the qualities or shortcomings of a person.

7. **Seek compromises**
In any dispute, it is important to seek balance and compromise. This does not mean giving in, but finding a solution that satisfies both parties.

8. **Use “I” statements**
When we say “I feel,” “it seems to me,” “I think,” we reduce the likelihood of conflict. This helps to express your feelings without blaming the other person.

9. **Be prepared for change**
Sometimes you need to change your point of view or approach to avoid conflict. Flexibility in thoughts and actions is an important quality.

10. **Put relationships first, not winning**
Conflict is not a competition. It is important to remember that the goal is not to win an argument, but to maintain and strengthen relationships.

These simple but effective rules will help you avoid many unnecessary conflicts and maintain harmony in your relationships. It is important to remember that any disagreement is an opportunity for growth and better understanding.
