Sometimes, the best thing you can do for your writing is to take a break. This is especially true during the editing phase. Let it sit for a day or week. Then go back to it with fresh eyes and a fresh brain.
It’s also good to take an occasional day away from your story to just go play, relax, have fun. Energize the creative side of you.
Of course, I don’t recommend taking a break if you’re on a roll or if you’re way behind deadline. But every once in a while, give it a rest.
And I’m going to follow my own advice. I’m having a medical procedure (routine, nothing serious) that requires follow-up pain killers and who knows what I’d write under that influence. So I’m taking a break for the rest of the week. Go browse through past posts—commenting on old posts enters you into the contest to win the books in the sidebar. Or head over to the LDS Fiction site. We’ve got new titles popping up every day for awhile.
