Personally I go for some sort of change.
If you are feeling burnt out on writing either give it a break or put in some time writing about things that don't matter but make you happy.
It makes no difference if they will never go anywhere beyond your hard drive.
I write things that are pure nonsense but amuse me. I recently wrote about the history of the Asstidon an ancient but intelligent predecessor of the mastodon and all of the other dons. They had multiple trunks with fingers and spent most of their time writing poetry. They became extinct after they discovered sitting, which was great for poetry but left them vulnerable to attack.
Now I'm working, playing, with a quest to find the West Pole.
I also take up new hobbies. I explore on my motorcycle, the first I've had in 40 years, and am about to start a search for all the best snorkeling places in my area of Southern Luzon.
I feel for you going into winter. We are just emerging from the Monsoon season, 4 months of almost endless rain. I'm guessing we had about 10' since the end of July and will have 12' for the year. Needles to say I'm more than a little stir crazy.
Maybe a motorcycle isn't your cup of tea and if you're not in a sun state not practical in winter. But consider taking up something that interests you and will be new.
When I lived in the states, CA, I took classes at the local community college often ones that were simply fun. I studied special effects make up for 2 years as well as make up for photography. I studied photography for close to 4 years taking every class from 101 to commercial view camera. I took airbrush classes though I'm no artist.
The thing I liked about taking classes was that even though I had a full schedule it forced me to take the break to make it to class at least once a week usually more. Somehow I was always able to fit it in and always returned home feeling relieved and with less stress.
I also took badminton playing twice a week, I've played since I was a kid. There is nothing like a sport to give yourself a stress break. If not a sport the gym is a good second choice, just make sure you actually go on a set schedule.
