You can't put a mirror on the table at home to look at yourself, which will lead to your inability to concentrate, anxiety, and even dizziness, poor rest, weakness and other symptoms.
It is very unlucky that the mirror can't shine on the seat. If it really doesn't work, you can put some plants next to the seat to backlight it.
The mirror at home should be placed in a dark place, which can make the light at home more comfortable.
