This weekend, I met a woman who talked about what she is passionate about. It was such a beautiful experience. She also said how she feels the beauty of the forest when she goes on a bike ride. 
It made me think about how I want to feel more gratitude. So I did some more Internet research and found this article. 

It gives an example on how to practice feeling more gratitude and it has lightheartedness in it. 

And a lot of it matches something I could have written.
