As much as I know I have in common with ppl my age range, I think it's important to remember that there's lots to be learned from those younger than me.
I think disregarding the lessons from younger ppl can be a real tragedy.
My woodcut teacher is the same age as my "baby" son. 20 years ago he couldn't have taught me a thing. Today, lessons learned!
Not only that but the energy and freshness of eye is contagious. I want and NEED to be with artists who haven't hit a rut and stayed in it. I think in that way, I'm kind of young at heart. It's what I disliked about an art group I was in...talented to be sure, but happy to stay in their zones.
And happily, I've found young artists are not ageist! It's the enthusiasm and commitment which matters, not the calendar!
