Don't Believe Everything You Think by Joseph Nguyen

Teaches that the root of human suffering is our own thinking, not external events. The book provides strategies to achieve mental freedom by recognizing that thoughts are not facts, cultivating non-judgmental awareness to observe thoughts without entanglement, and letting go of the struggle against them. By understanding the distinction between thought and reality, readers can reduce overthinking, anxiety, and self-doubt to live more peacefully and abundantly.
