Time is useless, looking up is half-life. What are they?

Time is useless, looking up is half-life. Let's say:

1. Time is good, it's useless, look up, it's already half-life! The first half is a bit mixed, at least not promiscuous, keep your partner, don't talk about your ex, and don't be disturbed by others!

2. The reason for the trouble is that you don't want the youth who can still walk around to become a memory, and don't wait until there is no capital to leave and run wildly on the road. The story is the greatest meaning of your later life. Time is good, you are useless, look up, life is short. Don't waste any more time, just play with people on the same frequency, stay up late and think too much!

3. Time flies. I have looked up for half my life. I once thought that 30 years old was far away, and I turned around and arrived at 18 years old. Experienced glitz, experienced a long time of events. Self-knowledge, mixed feelings, quiet collapse, full self-healing and helplessness are all life! What about the 30-year-old? Only 30! Come on, everything will be fine.

4. Time has passed, and half a lifetime has passed. Live up to the present, live up to the good.

I used to think that 30 years old was far away, but now I find that 18 years old has been a long time ago. Time has passed, and I have been looking forward to it for half my life. What a person should face in his life will eventually be faced. Overcome all difficulties and obstacles. Work hard for yourself in the first half of your life and protect your loved ones in the second half.
