It means that a person's life is often full of happiness and joy, which reflects a person's perception and choice of life. Even if a person's unhappiness lies in his inner thoughts, if you think life is pessimistic, then your life is pessimistic. If you have a positive attitude and can face life calmly, then your life is full of happiness.
Happiness is the greatest pursuit in our life. Only in this way can we feel the true meaning of happiness and have a happy life direction.
