The important thing is to keep things separate. Keep work “at work.” That is, keep it in the office and as best as you can, during designated work hours. Though it is sometimes necessary, don’t let the two blend too often. Don’t do work in bed or with family on the couch or at the table. This sets a bad precedent where you are neither focusing completely on loved ones nor completely on work.
It is also incredibly important to get out for breaks. Take them regularly. Take walks and short drives to clear your head and see the outdoors. Call a friend or family member for some meaningful connection. Exercise daily, eat healthily, hydrate during work hours (an easy thing to overlook), and continue to pursue the social activities and hobbies that bring you a sense of satisfaction.
