Learning that the world doesn't revolve around me, and that other people (and other animals) have rich and complex inner lives worthy of curiosity, dignity, and love (I can't be sure, but it feels like a healthy perspective). I'm in my 40s and this lesson, started in youth, is still sinking in. Having a child, and the commensurate second childhood, is a major impetus.
I was going to write something very similar to this. Not only does the world not revolve around me, but looking back on my sadly somewhat recent behavior in early-mid 40s, and feeling ashamed and embarrassed at my behaviour and how I've treated people in the past.
This is still a learning experience, probably always will be one, and an opportunity to always grow.
My impetus wasn't a child, but a break-up and almost lost business. I saved the business in the end, but it didn't grow to what I had expected, and then I realized how much I had given up, just to try to make that work, and how much I had taken for granted the people around me.
