I have no clue about the personal life of the OP, but I can share my case.

I have two small children (and an old one). During 2020 we had no kindergarten, no visits to grandma and no babysitter, because the lockdown was very strict here.

Also I teach in the first year of the university, and we had everything ready for the presencial clases as usual. We had to switch to virtual clases with a head-up of one month [1] [2].

So I had to drop my hobbies and reduce my research time and other not urgent activities.

[Note: A fixed weekly Zoom/Meet/Teams meeting with your friends helps a lot to keep your mental sanity.]

[1] How do you replace a blackboard? A real blackboard is very difficult to read in a Zoom/Meet/Teams meeting. A few of my coworker bought one, but had to switch to other methods.

[2] Moodle has like a thousand of options and it takes a lot of time to find the combination that is more similar to what you want and coordinate with your coworkers to find the best one.

To provide more anecdata, I consistently read more than in the original post. But I found myself reading less during 2020 even though I had more time to read.

I guess 2020 just sucked.

I get your point, but like I said, I didn't have the habit.

do you really need to belittle someone here
