There are many great writings, and each is unique in its own right. These are the writings I have found to be most influential in my quest for purpose:

1. The Bible

2. Tao Te Ching by Lao Tzu

3. Zen in the Art of Archery by Eugen Herrigel

4. Nature by Ralph Waldo Emerson

5. Man’s Search for Meaning by Viktor E. Frankl
