2. Understand that failure is a kind of happiness.
In fact, suffering also includes openness and tolerance, and it also adds reason and self-restraint. Being calm in the face of loss is a kind of self-confidence based on personal ability, but not everyone has this kind of self-confidence.
People who can suffer losses are often safe and happy all their lives. A person who can't suffer losses haggles over every ounce in the dispute between right and wrong, but he is limited to the narrow self-thinking of "not suffering losses", which will blind his eyes and will inevitably suffer greater disasters and eventually lose more. So losing is a blessing.
