You can't go anywhere? Just drive/rent a car and go somewhere within 2 hours, in nature. Muse on life, hike. Way more "productive" than anything else.

Nah, I can't go further than 20km away

Damn what country? Maybe just go for some hikes around and try some mushrooms.

Melbourne in Australia. Restrictions will be easing very soon though :)

But yeah basically lockdown in some form or another since mid March here
