3 books every Saas entrepreneurs owner should read

The other day I saw a post by somebody who was looking for book recommendations for Saas CEO's/ business owners. Unfortunately I couldn't find the post when I wanted to reply to it later that day. But nevertheless I wanted to share my top 3 book recommendations in the hope that these books would help someone else the same way they helped me-

1. From Impossible to Inevitable by Aaron Ross and Jason Lemkin

2. The Hard Thing About Hard Things: Building a Business When There Are No Easy Answers by Ben Horowitz

3. The Lean Startup by Eric Ries

It's important that one spends the time to train his mind before going on his entrepreneurial adventure. Good luck!
