Walk. Read. Write. Sketch.
Which are things that can easily (and cheaply) be done together. Go out have a walk, take a pocketbook, a pencil and a pocket notebook with you. Go sit in park, or any nice place you prefer, and start reading the book. Close the book. Get the pencil and notebook out of your pocket and start writing about what you just read. Or about the things you see around you. And why not sketch them too, using the same pencil and notebook?
Why do I bother carrying an extra pocketbook, notebook and a pencil and not simply use my phone? Easy: I want to enjoy those moments, I want them to help me feel better, not worse. With those there is notification to ruin the moment, there is constant anxiety and no fomo either.
Which, to me at least, is another very 'simple pleasure' I get in life: not having any social media apps on my phone.
