A sad and domineering sentence

1. People can only save themselves when they are in trouble. The key is how strong you are.

When you find that you always miss your family, you grow up.

3. "envy those who can sleep peacefully when they touch the pillow, and envy those who will never look back after putting it down."

4. You don't worry that nobody loves you. What you are worried about is that no one will love you the way you want. In the end, you will find that your worry is right: no one can love you the way you want, except yourself.

People who come into your life are all useful, good and bad, which make you happy and make you cry.
