All of our routines are being disrupted in some way right now. Even if you live in the basement and just play video games all day, we're all being affected. So how do you build a new routine and create some certainty in your life when every day is different?
Here's some ideas:
First, recognize that above all else, establishing a routine is more about having a sense of certainty than it is keeping an exact schedule. It's about knowing what to expect, and having a sense of familiarity with the outcome of each day. This sense of familiarity is on a spectrum, which means that too much familiarity leads to boredom and dullness (thats why people go on vacations and do new things in general).
Since we can recognize that there is a spectrum of certainty, instead of focusing on building a minute-by-minute schedule to adhere to, focus on building in more certainty into your life. Maybe you should cook the same thing for lunch every day for the next week. Maybe you set an alarm to wake up at a certain time, so that your day always starts the same way.
Again, building a routine is less about adhering to a schedule and more about creating a certain amount of certainty and knowledge of what to expect in your life. And since, in the outside world, what to expect is changing minute by minute, you'll need to make your own personal home life more certain and regular.
Stay safe, wash your hands, and we'll talk soon.
