What is the 1 book you would suggest everyone reads in their lifetime?

I'm making it a personal goal to read for 30 minutes daily again, and am looking for some quality material. Anything related to tech, startups, product, fiction, or woman's history are very interesting to me.

One of my favorite books that I read over and over again is The 48 Laws of Power by Robert Greene.  It's basically an in-depth study of what people to do attain power (usually through very devious means) and provides historical context on people that followed each law and also transgressed each law.  

I remember my wife complaining about the erratic behavior of some executives at one of her past jobs.  When she explained to me what they were doing, I could always loop it back to one of the 48 laws of power and I was able to walk her through it.  It actually gave her really good insight into the way her executives thought and worked.

Since the book is broken up into 48 chapters (one per law), it's easily digestible in short settings.  And it has a snazzy cover with the word POWER in big gold lettering on the front - definitely a good conversation starter if you whip it out on the subway or a coffee shop.

Now I wouldn't recommend actually following the laws in real life unless you a power hungry sociopath who doesn't care about other people (unless you can use them to increase / consolidate your power), but if you are trying to navigate a treacherous work environment it is a very enlightening read.

Current fiction book I'm loving is Private Citizen by Tony Tulathimutte.

Favorite startup book is The Hard Thing About Hard Things by Ben Horowitz.

When it comes to startups, my favorite book is The Lean Startup by Eric Reis. It's even a podcast which is great if you're on the subway or at the gym.
