Hobbies.

Hobbies are good to have. They teach you stuff and they're. Well, they're there. They're fun, I suppose. They're just important to have. But I don't really consider writing a hobby; partly because it was my job for so long, partly because it's something that if I don't do I'll shrivel up and die. Your hobby shouldn't be something that if you don't do it you'll die. That's bad.
I like puzzles. Puzzles are nice, and quiet, and they form pretty pictures. They don't require a lot of thinking, but they keep your brain engaged. They're... nice. I don't have a lot of nice things. I mean, well, yeah, I do. I have some great things in my life, but I don't mean 'nice' as in 'good,' I mean 'nice' as in 'will not abuse, cut, scratch, or maim me.' Luna is a nice thing but not a nice thing, you see?
I find sometimes that while I'm putting a puzzle together or... taking a nice walk or... you know, doing something that doesn't require a whole lot of thought but I relatively enjoy, my thoughts flow a lot easier. It's not writing, no, but it does relate, because I rarely have any good ideas about writing while I'm actually writing. Whenever I had to actually think of a poem for the Royal Courts and stuff, that was always my worst work. My best work always seemed to come out of nowhere, when I had my brain completely focused on something else instead of this or that task.
The trick is remembering those ideas, but... well, personally, I recommend either carrying a notebook everywhere or just... well. Remembering. Yes, I know, helpful. I don't know, though, it's like... after all the years I spent in the Northlands without being able to rely on being able to just, bust out my writing journal anytime I wanted, I kind of learned to dedicate part of my mind to just remembering weird stuff. Trivia, ideas, bits of verse and writing... I mean, it helps to associate it with something, yeah, but for me it's also just always kind of there, floating along the surface. I guess my brain's just kind of funny like that.
So. Yeah. Find a hobby, apart from writing. It'll help calm your focus, and it'll really help your mind... de-pressure from any writing you might do during the day.
Just. If it's puzzles, sometimes it's better not to let certain ponies 'help' you. Because certain ponies have to put everything in their mouths or throw pieces everywhere and they got lost to the void and that's why I haven't completed a single goddamn puzzle in years. This is why I dream of having an office. Or finally teaching Luna that not everything has to be thrown or spat at me. But one of those things is much more likely to happen than the other.
