David Albert, who wrote And the Skylark Sings With Me, says it's important for us to model learning new things with our children. He says that our kids need to see us struggle and persevere, since they tend to think everything comes easily to us.
I think he's probably right. Nevertheless, it's a heckuva lot easier to struggle and persevere when the kids are in bed. Maybe my concentration isn't what it used to be, but I find it challenging to learn new things while Star Wars figurines are being catapulted across the living room and I'm subjected to a perpetual "Can I have another peanut butter cookie?" mantra.
