Read books.
We all have a long, imaginary shelf of masterpieces we have not read. For years I was embarrassed by my ignorance of War and Peace, and Tolstoy's massive novel had sat on the shelf, glaring at me. Not until the mid-80s, when I passed a lovely spring on the Amalfi Coast of Italy in a tiny rented house, did I find myself ready to tackle it. I would rise at dawn (we had two babies then) and take my coffee to the terrace. There was a grove of lemon trees behind me, and I could look all the way down the coast from Amalfi to Salerno, the sunlight on the sea like scattered coins. I was absorbed for two months in that astonishing novel, making my first acquaintance with Pierre, Natasha, Bolkonsky, and the rest of Petersburg society. Forever I will associate that story with that place, and that time in my life.
I doubt you'll ever find yourself associating a YouTube video with a place and time in your life.
