Ask HN: My hours have been cut to 15h/wk. What to do with spare time with Corona

The cut was offered by my company as a way to scale down during the pandemic without cutting jobs and I took it. No big deal, it's still enough money and that's not the topic I want to discuss in this thread.

I'm getting seriously bored, but I can't come up with anything interesting to do with the spare time.

It would normally not be an issue: I'd play the console, go for a bike ride, read a book... But for some reason none of that is appealing right now.

How to deal with the extra time without going nuts while the pandemic is going on? How do you cope if you've been laid off or just hold a regular full time job where there is only 2-4h worth of work per day?
