Imagine everyone sitting down everyday and diligently typing out their novels--hour after hour--with no breaks, no doubts, and no crumbs on the keyboard. Yeah sure! Makes me laugh...ha ha...writers don't really do that. Do they? Can they?
Don't go wild and add everyone you know to your new email list... there are rules and laws around this practice and you could find yourself in receipt of a huge fine... and I mean HUGE!
Hearing your own work critiqued can lead to a knee-jerk reaction filled with defensive indignation. Others obviously didn't understand. You start to explain and try to bring them to a point of agreement, but it doesn't happen. You view the person doing the critique as an idiot--unworthy of being in the same room with your genius and a total waste of your time.
