Great topic GeoMamma!
I strongly agree that what we model for our kids is a lot more important than what we say. I encourage you to tackle something totally new and allow your child to observe your learning process. After reading about the adult learning journeys of hoemschool author David Albert, I made a conscious decision to try out a couple of new hobbies that pushed me out of my comfort zone. This process gave me greater empathy as a teacher and it helped me be a more effective parent. You can talk up and down and round and round about perseverance, perfectionism, etc. but your kids will see if what you actually live is very different. Also, there is quite a bit of research now showing lifelong learners tend to age better and keep greater mental acuity.
Do you have an ideas of something totally new you could try?
