I don't. I find my motivation to be the same, but it's far easier for me to focus at home; I've got fewer distractions there.

If I have any tips, first, try to figure out why you can't focus or you aren't motivated. If you can't focus because of a distraction and it can be removed, remove it. If it can't be removed, can you remove yourself (to another room or even outside for a bit)?

Getting motivated can be tough, because there's probably a million things that can factor into that and your job is only one of them. That takes some self reflection and maybe a friend to talk it over with. One clue you've given is that you seem to lament spending so many hours of your day at home. Prioritize getting outside when you can, if only for a walk. Work outside for a bit if you can.
