2 books

What have been some of the biggest influential books you’ve ever read? (changed the way you think about something, provided real value)

A friend asked me that yesterday and I couldn’t believe how few books have actually influenced how I work and act on a day to day. Most just don’t have that kind of staying power. In fact, there’s only 2 that immediately sprang to mind:

1. Rework
   Because it made me want to start a business that keeps things simple.

2. How to Win Friends and Influence People
   Because it changed how I approach people. Everyone pays lip service to it, few actually use the advice.

Crazy right? I’ve read hundreds of books in the last few years. Only two have stuck with me and really changed how I approach business.
