If you are not motivated to write, if it's a chore, if you have no drive to do so, DON'T! Find something you love, something you're driven to do, and DO THAT! You'll be happier, the people around you will be happier, and you'll give more to the world.
I have just saved you a lot of time, money, and frustration, and perhaps set you off on an exciting career in whatever you're excited about.
