Almost twenty years ago, I bought a small book written by Thomas Nagel titled What Does It All Mean? Since then, I have read it many times over, lost it, and bought it again. Only to have it lost again and, this time, found.
This tiny volume is only 101 pages long, which is divided into ten small chapters: Introduction, How Do We Know Anything?, Other Minds, The Mind-Body Problem, The Meaning of Words, Free Will, Right and Wrong, Justice, Death, and The Meaning of Life.
This book provided a structure on how I should look at life, its meaning, and death. It is a philosophy book, yet it is so practical and applicable, unlike those esoteric volumes by big names who lived a few centuries ago.
I learned to approach every decision and every event in life with a pair of critical eyes and critical mind since I finished reading it in one sitting.
