I think the most difficult thing on remote working is to not get sidetracked. Which, lets be honest, is easy in a bad home environment (screaming kids anyone?) or if you dont have military-level discipline.
So what do you do to keep yourselves accountable, productive and efficient when "working and no one is watching"?
I think the routine of getting a certain number of things done first thing can set up a nice productive day. If I finish or ship anything early on in the day, it can lead to a generally productive day/week.
If I let myself get too sidetracked early on, it can linger all day as just one more distraction after another.
