From my close observation of writers... they fall into two groups: 1) those who bleed copiously and visibly at any bad review, and 2) those who bleed copiously and secretly at any bad review. ↗
There is no magic. There is no secret. You need your sleep. A lot of our society tries to get by, but the truth is it is up to each individual to get their optimal sleep amount. If you get less than that you can get by temporarily, but it's only temporary. ↗
