You try to smile naturally, and then look at the way you smile so that it is not annoying. In fact, as long as you keep smiling, your mentality and the state of the whole person are completely different from the feelings you give others. From ancient times to the present, there are too many people who are ugly but have remarkable effects, but they have not had plastic surgery. That is the problem of mentality. They believe that they can solve their own problems, and they must have their own advantages in other aspects, so they will foster strengths and avoid weaknesses and face difficulties bravely. Never run away from you because of inferiority complex. Believe in yourself, God doesn't give you enough looks. He must have given you capital that is superior to others in other aspects, and this capital is waiting for a confident person to discover and explore. Even if you fall, laugh bravely. You will enter a good position because of your unyielding. I sincerely wish you success and be yourself! Win people's respect and affirmation!
