What are some philosophical classic insights into life?

1. If you are not brave, no one will be strong for you. If you are not crazy, no one will help you realize your dream. If you don't cherish it, no one will feel sorry for you. If you don't persist, no one will fight with you. All things are imperfect and all life has shortcomings. 2. Don't care what others think about you behind your back, because those who are better than you don't bother to mention you at all. 3. If it’s really hard, you won’t have time to complain. If it's so miserable, you won't have time to feel embarrassed. Because you haven't endured enough, you have time to complain. 4. Life is like a cup of tea. It will not be bitter for a lifetime, but it will always be bitter for a while. 5. There is no rehearsal in life, every day is a live broadcast. Grasping every performance is the best way to cherish life. 6. If you can't accompany me to the end, don't enter my life halfway. You know, I can get used to being alone, but neither of us can accept that I was alone when I was with someone.
