In addition, you may have been engaged in intense exercise recently, causing people to lose strength at work and be in a state of fatigue without recovery. At this time, you need to pay attention to the amount of exercise. This is the case with a friend of mine. He didn't run for many days, and one night he suddenly went running. After running for a long time, he did a lot of exercise, which caused him to have no spirit at all the next day, so he slowly reduced his exercise. If you look at yourself this way, you can refer to this practice.
Furthermore, if the above two situations do not match, it may be that you are really not in the state, or that you are lazy because you have no goals and no pressure. After a long time, people will naturally become decadent like this (in other words, they are actually idle). This is also the experience of front-end time. If you work too much in the future, you will be very busy and have no energy to think about it. Every day is a day. So if so, you need to keep yourself busy.
