Getting yourself into a state of high concentration is usually a good way to deal with loneliness. For example, watching movies, listening to music and reading books. I often turn to writing, especially the writing desire aroused after reading is immediate to my heuristic thinking. I personally like the feelings inspired by the author's views and words. Although I didn't talk to the author face to face, I was definitely not lonely at those moments.
We must be lonely anyway. We should fly away and be lonely again, or we would rather be alone on high places. After reaching a certain height, we can even pursue the sense of superiority brought by loneliness. How lonely invincible is. How many people want to climb to the top of the mountain and feel the moment when "I pulled out my dagger and I peeked at the road for nothing".
