In interpersonal communication, make friends widely, but carefully choose friends who are really good to you, instead of keeping casual acquaintances with many people.

Make more friends and less heart-to-heart. Emphasize the importance of sincere friendship. Make friends with quality rather than quantity. In real life, you will meet many people, but not all of them can become true bosom friends. Establish deep friendship with friends who are really kind to you and can support each other, and can give you comfort and support when you are in trouble.
