Twenty gratitude affirmations for the natural world — for the sun, the shade, the breeze, and everything you stopped seeing.

Gratitude for the natural world is unusually easy to feel and unusually easy to skip. Nobody has to be persuaded that a sunset is worth something. It is just that the sunset happens while you are answering an email.
These twenty affirmations are small enough to fit into a normal day. They name the specific things — warmth, shade, colour, quiet — rather than nature as an abstraction, because gratitude works better when it has something particular to hold on to.
"I am grateful for nature" is true and does almost nothing. "I appreciate the warmth of the sun on my skin" gives your attention a job. The narrower the line, the more of it you actually feel.
Try one a day rather than the whole list. A single specific thanks noticed properly on a Tuesday beats twenty read quickly and forgotten by lunch.

Yes, and for many people it is the easiest entry point. It asks nothing of your relationships or your circumstances, which is useful on days when those are the difficult part.
Either works, but say them outdoors if you can. Reading a line about the breeze while the breeze is actually on your face is a different experience from reading it at a desk.
Then be grateful for something the weather is doing — rain on a window, cold air that wakes you up. Restricting gratitude to good weather halves the number of days you can practise.
They work well out loud on a walk, one line each, taking turns to find the thing being named. The naming game is the practice.
