Give yourself office hours.
Don’t answer the phone or the door (emergencies excepted). Don’t turn on the television (the Kindle counts). Turn off the WiFi. Get yourself in office mode. I make a cup of tea. On occasion, I’ll light a scented candle, but it’s not particularly my go-to; it’s just a sometimes go-to.
My husband works at home, and he’s always interrupting me, so I will need to remind him that I’m working even if all I’m doing is staring into space, chewing on a pencil eraser.
My kids are also home by 3, so my hours need to end by then during the school week.
I also try to attend mass three times during the week, so my hours are worked around those times.
My basic hours are 10-3, although I will write at other times; I make my writing portable enough that I can jot things down anywhere.
Work around your life, but be diligent. Any and all writing is good writing during Nanowrimo. Edits are for December.
