Write the kind of story you would like to read. People will give you all sorts of advice about writing, but if you are not writing something you like, no one else will like it either.
Keep going on hikes, keep having your friends in your life, keep that downtime sacred as well because as hard as you work in any job, it's really nice to have the relaxing de-stressors. Stress is the worst thing. That's the ultimate demise of any good thing.
