It’s definitely harder with kids, but I’ve actually used my kids as a catalyst for learning. There are loads of hobbies and activities I’ve taken up just as a way to expose them to the world.
To be honest I did those kinda things already, except for the singing, but having a small child those are the kinda things he likes at the moment. No doubt his tastes will change over time, but I'm gonna try to join in with his interests at least until such time as he doesnt' want his "uncool" dad doing so.
It was a great opportunity to teach them some things and learn others too. Especially unusual things like washing houses (I do not know the English word for that, these are places people were coming to wash their clothes, usually a water source and stone washing places, under a roof). Their history was surprisingly interesting.
