What message did Johnny send Ponyboy?

From the text:

Ponyboy, I asked the nurse to give you this book so you could finish it. It was Johnny's handwriting. I went on reading, almost hearing Johnny's quiet voice. The doctor came in a while ago but I knew anyway. I keep getting tireder and tireder. Listen, I don't mind dying now. It's worth it. It's worth saving those kids. Their lives are worth more than mine, they have more to live for. Some of their parents came by to thank me and I know it was worth it. Tell Dally it's worth it. I'm just going to miss you guys. I've been thinking about it, and that poem, that guy that wrote it, he meant you're gold when you're a kid, like green. When you're a kid everything's new, dawn. It's just when you get used to everything that it's day. Like the way you dig sunsets, Pony. That's gold. Keep that way, it's a good way to be. I want you to tell Dally to look at one. He'll probably think you're crazy, but ask for me. I don't think he's ever really seen a sunset. And don't be so bugged over being a greaser. You still have a lot of time to make yourself be what you want. There's still lots of good in the world. Tell Dally. I don't think he knows. Your buddy, Johnny.

He means stay delightful this may be wrong but i thought thats what he meant
