What should I do if I have been particularly unlucky recently?

I had this stage. This situation is usually that things have not gone smoothly recently, leading to two consecutive mistakes. At this time, you'd better stop, relax and don't be too nervous. You can sing and adjust your mind. On the other hand, you should get some improvement by keeping enough sleep. Don't screw this up. I will do my best to the end. This often backfires and it will never rain alone.
