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?
First thing is to allow yourself to be bored for a while. Decide not to do anything till a fixed date. Ideas will pop up and just write those down (on paper) as they do. Limit your time on internet for 1-2 hours a day. Sleep more and exercise a bit (do not strain). Within a week you should see your mood improved and will have fresh ideas.
For me the low-workload period was long (approx 1.5 years). I learnt music, stock-trading and some new recipes for cooking.
