1. You have to exercise. This is not an option.
When you work from home, it’s easy to slip into the habit of staying inside all day. This is really, really bad for you. And not just for your physical health — for your mental health. In the first couple years of my freelancing life, I slipped into a depression in large part because I was isolated and wasn’t working out. Not everyone’s depression is the same. But mine virtually evaporates when I start exercising regularly. If I want to be productive, I no longer consider it an option.
