Don't show off happiness, don't show off sweetness, don't show off success, don't show off all your beauty. The basic knowledge of physics tells us that exposure will always lead to water loss; hiding is the best way to preserve freshness. Gradually, you'll understand that life is your own, and it has nothing to do with others. High-level people are all about restraining their sharp edges; only low-level people like to flaunt themselves. If you share your happiness with the wrong person, it becomes showing off and invites jealousy. If you share your feelings with the wrong person, it becomes pretentious. If you share your sadness with the wrong person, it becomes a joke. Happiness is nurturing your own heart, not nourishing others' eyes. In a person's life, besides genuine happiness and health that cannot be stolen, there is nothing worth showing off. Clear the clouds to see the sun, and view the scenery above the clouds.
