Why Positive Thinking Can Backfire Even if you try to fill your inner world with positive thoughts to attract "good luck," our hearts are already overflowing with many negative thoughts. Therefore, even if you try to have positive thoughts without eliminating those negative thoughts, the power of the negative thoughts already present in your heart will negate the power of the positive thoughts. Furthermore, when you force yourself to have positive thoughts, our hearts have a "bipolar nature," and negative thoughts will conversely arise in the unconscious world. Therefore, positive thinking often backfires. The back cover is slightly bent. Otherwise, it is in good condition.
