Never enjoyed until you got older

What's something you never enjoyed until you got older?

This is a tough one for me. I probably have a long list. But for one being alone. When I was younger, I liked friends and party and always been with someone and doing something. Now, as I get older, I don't mind being alone. Just enjoying my house and my property and walking around. I still have friends over, but it's not like it used to be.
