1. The main point is that people should live soberly and meaningfully, and should not follow the crowd or wander around. Think more about everything, the pain of being awake is much better than being confused.

2. I think this passage means: The meaning of time is to look forward, don’t be too obsessed with past memories, and spend time on planning for the future. The other thing is to be realistic and not indulge in fantasy, because that is just a fantasy, has no practical significance, and will not increase the thickness of time.

3. For life, this topic is too big. I can only talk casually. Talking about the realm of existence reminds me of the words of my writing teacher. He said that the ultimate meaning of life is to enjoy life, and your vision, height of awareness, and quality determine how you live your life. And these efforts are to enjoy life better. Only when your own height increases, your state of existence will be different. In fact, this does not specifically refer to material conditions. I think it is more about spiritual things. Some people may have great wealth, but their spirit is poor. As for me, I think that I need to have basic material security, and at the same time strive to improve my various qualities to achieve spiritual enjoyment and freedom. This state of existence is what I hope for.

I talked a little bit, I hope it will be helpful to you, please adopt it if you find it useful.
