Four sentences from the Mao Zedong Thought can solve ninety percent of anxiety:

1. The worse the situation, the more we need strategic resolve. Don't follow others in complaining; when others complain, their minds are already troubled.
2. Actively finding solutions is the way to solve problems. Only by believing that no problem is unsolvable can we have the ability to resolve all issues.
3. Don't get angry when hearing different opinions, thinking it's disrespectful to oneself. This is one of the conditions for treating others with equality.
4. When one contradiction is resolved, another arises. Contradictions always exist in people, places, and times. Without contradictions, there would be no world.
The Mao Zedong Thought is a guidebook for practical life; it is a classic worth deep, careful, and continuous reading.
