Sometimes we become masters at procrastination - I think I have a Master's Degree!!!
Remember: Keep Writing.
My tip is to do writing sprints - start with a low number of words. I'm doing 250 at the moment on my WIP (Work In Process), but you can choose whatever word count works for you.
The rules are you do not get off your seat (for anything or anyone!) until you've completed your number of words. Plus turn the internet off - no emails, no checking FB (the cats will be there when you back!). If you get into the story flow, keep going!
Try to do as many writing sprints as you can within a day - 4 a day x 250 words and you've advanced your MS by a 1000 words. How cool is that!
Set writing goals & stay positive!
Take care & keep writing,
