Many times, what people call 'writer's block' is the confusion that happens when a writer has a great idea, but their writing skill is not up to the task of putting that idea down on paper. I think that learning the craft of writing is critical.
Putting words on paper regularly is part of the necessary discipline of writing. A journal is a great way to do that.
But it is the fear, not the writing that defeats me. Everything is not a masterpiece.
I think it's hard to make a living as a writer, but I think it's hard to work at McDonald's too.... I think the commitment is to get up everyday and say, "I'm a writer, therefore what I'm supposed to do today is write." And to do that, and to do that and to do that.
I really love writing comedy. Writing romantic comedy is even nicer because you get to write about how insane we all act when we're falling in love.
