There is life outside your apartment.
Or house, or office. If you work from home as I do, it’s far too easy to become a hermit because you sleep, eat and work at home. This isn’t particularly healthy, especially as most of that time is sitting in front of a computer. Try and go outside at least once a day – go for a walk, buy groceries, go to the gym, meet up with friends or colleagues. Fresh air and human contact does wonders for physical health, mental health and creativity. So if you’ve gone a few days without leaving your home or speaking (out loud!) to another human being, GET OUT THERE.
