There's a rule of writing: if everything is funny, nothing is funny; if everything is sad, nothing is sad. You want that contrast.
Writers write for one reason: to create an emotion in the reader, to reach across and make them feel something. You want a reaction. Yeah, it's nicer when the reaction is to throw flowers than it is to throw brickbats, but you have to accept both equally.
My philosophy: find what it is you want to say, walk in the room, say it, and get the hell out.
The hardest thing in the world is to stand alone. Your friends will not understand, will resent you, will want you to just stop it and let life go back to where it was. But you have to follow the quiet turning of your own considered conscience. It's a hard road.
I've changed my mind. I've decided that at the end I want to be cremated and my ashes scattered over someone I don't like.
