Maybe you know you have to stay up less, but for some objective reasons, you can't do it at all. So I think sometimes, it's not that we don't want to go to bed early, but that there are some things to be done in front of us, so we can't go to bed early at all.
Because sometimes, the leader may ask us to work overtime temporarily, or give you a lot of tasks at night, then you know that you must finish it tonight and hand it in tomorrow morning, and you can't just go to bed so early. Must be completed. Then I think this is also a common feature of contemporary young people's life, either because of work or because they can't let go of their love for electronic products, and they may have to chase dramas or play games in the middle of the night.
I can't go to bed early at all, so I think it's probably because young people are energetic and used to going to bed late. So although many people laugh at young people staying up late to use the most expensive skin care products, it is actually a helpless move for them. When they realize that such behavior is very harmful to their health, they will choose to change, so I don't think we need to worry too much about this problem.
Sometimes, there are irresistible factors in life. Just get through this period. If you want to succeed, you have to pay a little price. Accept it.
