Figuring out how to squeeze in writing time can be tough. Sometimes the great outdoors calls, sometimes just curling up reading a book or watching a movie has more appeal than writing.
One way I’ve fought doing something I’m itching to do rather than get on with my writing is to first of all get the writing out of the way. Sit down for 30 minutes and in the back of your mind know that once it’s done you’ve got the rest of the day, evening, whatever to go play. If you do it the other way round then the writing seldom gets done.
