The number 1 thing I learned from this book was you have to learn that selling is basically helping people and #2 that your product is the best thing for your customer, i.e. you should be convinced that there is nothing better in the world at the moment to help your customer.

When you truly and honestly believe that selling becomes easy.

Tough to call. I got a lot out of Deep Work by Cal Newport, The Obstacle Is The Way by Ryan Holiday, How To Win At The Sport Of Business by Mark Cuban, Thinking Fast and Slow by Daniel Kahneman, and The Engines of Creation by Eric Drexler, as well as the three Grant Cardone books I read: The 10x Rule, Sell or Be Sold and Be Obsessed or Be Average.

Fiction:

I'll go with The Whispering Room by Dean Koontz. A Wild Sheep Chase by Haruki Murakami was also pretty good.

10X

Both by Grant Cardone

In addition to Sell or Be Sold and The 10x Rule, I'd also suggest Be Obsessed or Be Average.
