I learned that, even as I grow undeniably old, my ability to learn new things - and my interest in doing so - doesn't wane.

I also learned a lot about working around the parts of my brain and body that aren't as limber as they once were, in order to keep learning/doing/enjoying life.

I learned - and continue to learn - that learning never stops, that we are all works in progress and that the journey is way more important than the destination.
