I've been working from home for almost four years. It takes some discipline. I miss the social aspect, though. I feel a bit too isolated. Going to a coffee shop and working from there, for me, is too much distraction. I do it every now and then when I need to get out, but mostly, I'm in my home office.

Yeah, like @hipkiss91 said. At office I'm more productive, why? well you have less distraction and are somehow obligated to work and be productive while at home you have a lot of distractions, you can easily say: 'I'm going to take a break of 10 minutes' and then those 10 minutes turn into an hour , 6 hrs and the whole day. So yeah, at least go to a coffee shop like starbucks and work there or library.

more comfortable or more productive......?
