All that was exactly me until Christmas year before last when my wife bought me an ereader. I carry it with me everywhere and read so much more because of it.
You'd be surprised how much reading you can get done on lunch breaks and waiting in lines! 5/10 minutes at a time add up to a lot of reading eventually.
I still play games and watch videos at home, but replacing phone scrolling with a book has done me wonders. Highly recommend.
Juggling is a really low barrier to entry that I picked up fairly quickly! Definitely keeps your brain active while doing it. Great for hand eye coordination obviously.
