Do not install Slack or MS Teams or whatever IM tools you use in your org on your phone.

Do not work for more than 8-9 hours a day. In fact, 6 hours of focused work is more than what you can do in a day.

Do not work after 10 PM if possible.

Go for a walk every day—get 20 mins in the morning, get 20 mins after lunch, get 20 mins during the twilight.

Keep your evenings free (typically 2-3 hours from 4 or 5 PM). Do what you love, take your eyes off the screen.

Make exceptions when needed.
