What else should I add to the collection

I currently have Meditations by Marcus Aurelius, The Way of the Samurai by Inazō Nitobe, Egyptian Book of the Dead, The Art of War by Sun Tzu, The book of Five Rings by Miyamoto Musashi, and Mans search For Meaning by Frankl. I’m planning on buying The Stranger by Albert Camus, On the Shortness of Life by Seneca, Letters from a stoic by Seneca, and Tao Te Ching by Lao Tzu. What else should I add to the list
