At some point, you get to accept the freedom this idea gives to you. And with that, comes not only appreciation of big moments of leisure and joy (like what you described as writing poetry and listening to cicadas), but also little moments of everyday life.

• A cute cat runs across the road
• Flowers bloom around
• A smell of recently mown grass fills the air
• Someone has made an art on the wall
• Someone wore a shirt with the inscription that made you smile
• People across talk about a BBQ party, or how quickly kids grow up, or plan a new friends meeting
• A stranger needs help. Maybe you can offer one, and you'll wish each other a good day?

There are millions of such moments happening every day. Keep an eye out of them, and you'll see the life happens all the time, not only on vacations.
