Here is a small “nugget” that someone shared with me some time ago.  I will modify it a little for you since you work at home.  While you are working at home, I am assuming that you are working in an office.  That is your “work domain”.  When you leave your “work domain”, leave all things associated with it in that room.  Make the doorway that point.  I do the same thing.  I drive the say way home every day.  There is a certain river that I drive over every day on my way home.  When I hit that bridge, I stop worrying about the things at work.  That doesn’t mean that I forget that they are there, but it does help me in ensuring that they don’t effect me later in the day.  I hope this (along with Curious George) will help you as much as it has helped me the past several years.
