1. As long as your heart is cruel enough, nothing in this world will make you sad. If you don't work hard now, you will move the bricks that others knock on the wall in the future. Our greatest kindness is to be polite to strangers, be patient with our families, be considerate to our lovers and not disturb the elderly. 4. Be nice to yourself once in a while, steal a little lazy, be a little crazy, and spend a little money, which will do no good. People still have to dream, even salted fish, but also to make the saltiest kind. 6. If my words hurt your inner pain point, please tell me, and I will concentrate my firepower in the future.
