Some of the books I enjoyed the most and found most helpful:

- Quiet: The Power of Introverts in a World That Can't Stop Talking by Susan Cain - Helped me better understand myself and others, highly recommend

- The Inner Game of Tennis by W. Timothy Gallwey - Advice on mastering the mental part of doing anything, not just tennis

- The Life-Changing Magic of Tidying Up by Marie Kondo - actually maybe the most important book I've read in a while, helped me throw away a lot of stuff I didn't need

- Models by Mark Manson - very helpful and ethical advice on attracting women for people like me who never really quite figured it out

- A Guide to the Good Life: The Ancient Art of Stoic Joy by William B. Irvine- discussion of a philosophy of life that seems like it would work well for modern living
