I myself have found out that during meetings I prefer to use a pen and paper but it is mostly just notes that I take for myself.
The summaries always go out as emails, of course, and if I paper note-take, I try to take a picture and upload it to onenote or sharepoint.
The trello part is more recent, but I have notebooks going back to my first internship in 2012(which I know isn't that long for most here). It's pretty interesting to see old notes I took and the problems I had at the time.
As a result I exclusively use pen-and-paper for meetings. I also started using fountain pens about two years ago and the discipline required to write well, especially with vintage flexible nib pens, helps keep me focused on note-taking.
Later on, wasting time reading NNTP news at the uni was also actually a good investment for learning the language in a way that is useful at work.
For my kids, the games have again been the same thing, along with Harry Potter books.
Then when I was 22, after a good computer science education, my first job was working at EA, and the build system involved a bunch of batch files. That knowledge from nearly a decade before came in handy! The CS stuff didn't come up until later.
