Several years ago, I had the ever living s*** kicked out of me in a post for talking about a writing exercise I did that worked wonders. I was hesitant to repost about it, but if it helps you...here goes.
Take a chunk of time and block out everyone and everything. Friends, family, loved ones, television, wifi, everything. Hunker down in a quiet, secluded place where there are no people to distract you. If you have to, rent a hotel room or a campground or a cabin in the woods. Put your writing first just this once. Then sit down and start typing. Whatever comes out, comes out. But you may find that without the distractions of everyone and everything in your every day life, you may come up with something wonderful.
Example:Arthur Miller locked himself away for weeks (either 3 or 6, I forget) until Death of a Salesman was complete--and look at what came of it!
Naturally, there are exceptions, like if you have kids or pets no one can take care of for you. But if you can go Rambo and scamper off into the woods for a week, DO IT.
