Start small.... just go pack your socks. Then stop back in and read a bit... then pack just your underwear drawer.... a little bit here and there. Pretty soon, a momentum builds.
Just like everything, I guess. It starts with little stuff... then builds.
I like the idea of believing that this is not the END ALL OF EVERYTHING. This could be just some time apart while you work on your stuff and he works on his.... people do that.
