There has to be something wrong with you to do this well, I think.  Some writers happen to be mentally balanced individuals that can compartmentalize appropriately.  Others of us are prone to a spectrum of dysfunction.  Depression, obsessive compulsion, substance dependency, insomnia.

I do not know which version creates the better work.  I do know that the one person who protects me from myself is very good, and is very much better than I am, and that I owe her more than she will ever owe me.  Thank heavens I am not crazy enough to forget that.
