This reminds me of this conversation from one of the books I am currently reading - So Big by Edna Ferber
In the first chapter, the father who is a professional gambler is having this conversation with his young daughter after a play, which he brings her to even though it is not the place for young girls to be seen.

> “The thing I like about plays and books is that anything can happen. Anything! You never know,” Selina said, after one of these evenings.

> “No different from life,” Simeon Peake assured her. “You’ve no idea the things that happen to you if you just relax and take them as they come.”

> Curiously enough, Simeon Peake said this, not through ignorance, but deliberately and with reason. In his way and day he was a very modern father. “I want you to see all kinds,” he would say to her. “I want you to realize that this whole thing is just a grand adventure. A fine show. The trick is to play in it and look at it at the same time.”

> “What whole thing?”

> “Living. All mixed up. The more kinds of people you see, and the more things you do, and the more things that happen to you, the richer you are. Even if they’re not pleasant things. That’s living. Remember, no matter what happens, good or bad, it’s just so much”—he used the gambler’s term, unconsciously—“just so much velvet.”

And this really got me thinking for days. And even now, I think if we can just take life as is, without getting overly attached but just moving along, enjoying and learning... oh, what a grand adventure it would be ;D
