You took the holidays off. Good for you! Now, comes the task of reentering your work. It can feel nearly impossible, at times, having to push back into a space that feels uninviting, annoying, and unnatural. This is the problem with too many days off.
To get you back in, I want you to think of two places in your primary writing project that still need attention, preferably something you can do without too much preparation.
Now, assign heads to one, and tails to the other. Flip coin. Enter work, and see if you can even write 50 words. If you want to stop after fifty, that is up to you. Once you do that, you have at least broken the seal. Your in.
