Hold on, you gotta let go
I was thinking how enraptured we have to be with our writing in order to get to those fabulous words, The End (which, by the way, no one types anymore, but it sounded good to say it anyway). I'm talking months of writing time with real life weaving in and out of the rapture, pulling you this way and that, distracting you, compromising your well laid out plot and character voice. I know I write better when I am absolutely drenched with the character(s) thoughts and mannerisms. Sound familiar? How do you keep yourself motivated with your writing? Do you need to role play, or does it come to you naturally the minute you sit down? Everyone's different!
Others might find what we do a rather childish occupation. "What do you mean you just spent an hour talking to a fictional character in your head?" Don't worry about it. We are so lucky to get to do this! This whole pretend thing that we do is what makes it so insanely fun, and it's necessary. Writing isn't just about being able to put together a great sentence over and over until you hit the last word. It is about creating something special that others can escape to. The only way to do that is for you, yourself, to escape.
I think one of the biggest reasons we experience writer's block is because we stopped believing in the character world; we were yanked out by some real-life experience, or someone told us it was all stupid or the voice was bad. Believe in the voice, believe in the world of your story, and the rest will follow.
