I used to go out in the morning to a local Starbucks and do email and planning tasks plus also get some social interaction. That worked really well for staring the day with a clear boundary.

At the end of the day I'd walk up to the train station (through a park) to meet my wife, so I'd have a clear boundary on both ends of my day. It worked really well while I lived there. Now I'm in a small town and it's a bit harder to do something similar.

I do this. I work from home mostly as my companies office is an 8 hour flight away. I have a standup first thing in the morning and try get a bike ride or gym session in at the end of the day. I also have a table in an office that is a 40 minute bike ride away however I feel better and more productive when I work from home with this schedule.
