Today’s wireless technology allows us to work from almost any room, but I suggest you pick one and make it yours. I always recommend setting a home office up in a room with a door that closes and locks, rather than at the dining-room table or in an open-concept loft or basement. For business calls and for concentration, it’s best to have a door for privacy. If you need to share a space, try to make it the guest room or a place that isn’t occupied by others during the day.
