5 Sales Bibles For Influence!

People who are in sales are a rare breed.

I’m talking about you and me.

Because we’re responsible for not just feeding our own families, but the entire company and its employees.

And that’s why, with the year ending…

I want to arm you with secret powers so powerful, the next time you speak with anyone, they’ll be under your influence before they even realize it.

But before I reveal these books, let me be clear about one thing...

I don’t want you to read hundreds of sales books and end up confused, overwhelmed, and lost.

Instead, I’ve curated the only five books you’ll ever need to read in your entire life.

Read these, master their principles, and revise them from time to time to measure your growth.

But here’s a warning:

Read these books at your own risk and promise me one thing...

Never use them for evil.

You promise?

Okay, cool!

Then let’s dive into the 5 Sales Bibles that should’ve been banned and never made public.

Let’s start with book #5.

#5 SPIN Selling by Neil Rackham

It’s an old book, really old.

Written in 1988 by Neil Rackham, former president and founder of Huthwaite Corporation, it might seem like a relic from the past.

But don’t let its age fool you.

This book is the foundation of modern sales psychology.

And here’s the kicker:

It’s not just some theory dreamed up in an office.

Neil Rackham and his team studied over 35,000 sales calls and spent a jaw-dropping $1 million on research back in the ‘80s to uncover what really works in sales.

Crazy, right?

Here’s why you should read it:

Rackham answers burning questions like…

"What makes success in major sales?"
"Why do closing techniques work in small sales but fail in larger ones?"

In this book, you’ll learn why traditional sales methods designed for small consumer sales fall flat in big-ticket deals and why conventional selling is doomed to fail in major sales.

It’s packed with real-world examples, illuminating graphics, and informative case studies, all backed by hard data.

And here’s what makes it so special…

While most sales books focus on tactics, SPIN Selling dives deep into strategy.

It doesn’t just tell you what to say—it teaches you how to think.

That’s the kind of mindset every salesperson needs.

In simple words, this book is timeless.

The principles work in any market, in any era.

And that’s why it’s still unbeatable.

Now, let’s move on to the next powerhouse...

#4 The Psychology of Selling by Brian Tracy

If SPIN Selling lays the foundation, then The Psychology of Selling builds the mansion.

Brian Tracy, a legend in the world of sales, doesn’t just give you strategies…

But, he rewires your mind to think and act like a top performer.

Let me tell you what makes this book so special…

Tracy dives into the psychological triggers that drive buying decisions.

He explains how the human brain processes trust, urgency, and desire—three pillars of every sale.

You’ll learn why people buy and how you can tap into their emotions, behaviors, and thought patterns.

He reveals how to…

• Overcome fear and rejection (because let’s be honest, we all face it).

• Position yourself as the ultimate problem solver your prospects can’t resist.

• Control your mindset, because your biggest competitor is your own self-doubt.

This book is like having a sales coach whispering in your ear, showing you how to close deals while keeping your integrity intact.

You following me so far?

Good.

Now, let’s move on to book #3…

#3 Influence: The Psychology of Persuasion by Robert B. Cialdini

Let’s get real for a moment.

Sales isn’t just about pitching your product or service.

It’s about understanding what makes people tick and guiding them toward a decision without them even realizing you’re doing it.

And that’s exactly what Influence by Robert B. Cialdini teaches you.

This isn’t your average sales book.

It’s like unlocking the secret playbook to human behavior.

It’s the kind of book that makes you go, “Ah, so that’s why people act the way they do.”

Cialdini spent years studying the psychology of persuasion, and he uncovered six powerful principles that drive every decision we make:

1. Reciprocity – People feel compelled to give back when you give to them first.

2. Commitment & Consistency – Once someone makes a small commitment, they’ll work hard to stay consistent with it.

3. Social Proof – People look at what others are doing to decide what they should do.

4. Authority – We naturally trust and follow experts or leaders.

5. Liking – We say “yes” to people we genuinely like.

6. Scarcity – The fear of missing out (FOMO) is one of the strongest motivators.

I mean these principles aren’t complicated and something new.

They’re simple, and timeless.

But incredibly effective.

Read this book, and you’ll start seeing these principles at play everywhere, in ads, in conversations, and even in your own decision-making.

It’s a game-changer.

Alright, ready for book #2?

Let’s go.

#2 The 48 Laws of Power by Robert Greene

Alright, let’s talk about The 48 Laws of Power.

This isn’t just a book.

It’s a manual for navigating the complex dynamics of influence, authority, and control.

In fact, it’s so powerful that it’s banned in American prisons.

Why?

Because it teaches you how to outmaneuver anyone, anywhere, under any circumstances.

And Robert Greene didn’t just dream up these laws.

He studied history’s most cunning leaders, strategists, and power players.

Think Napoleon, Machiavelli, and Sun Tzu, and distilled their moves into 48 timeless principles.

But this isn’t about manipulation.

It’s about understanding power.

How it works, how to wield it wisely, and how to protect yourself from those who misuse it.

Here’s why every salesperson must read this:

1. Power Dynamics Are Everywhere
   From tough negotiations to high-stakes deals, understanding the flow of power puts you in control.
   

2. It Sharpens Your Influence
   Greene’s laws teach you how to position yourself as the go-to expert without screaming, “I’m the best.”
   

3. It Decodes Human Behavior
   You’ll gain the ability to read people—what drives them, what they fear, and how to guide their decisions.

But let me give you a fair warning:

This book is not for the faint-hearted.

Some laws are ruthless.

You might even disagree with a few.

But understanding power doesn’t mean abusing it.

Right?

Well if you used it ethically, then The 48 Laws of Power will help you command respect, build stronger relationships, and close deals like never before.

You see, it’s more than a book.

It’s a blueprint for survival and success in a competitive world.

Now, if you’re ready for the #1 book that’s going to revolutionize how you think about sales forever, give me a clap and read on!

#1 Never Split the Difference by Chris Voss

Written by Chris Voss, a former FBI hostage negotiator, this book flips everything you thought you knew about persuasion on its head.

Voss used techniques so simple yet so powerful that you don’t need to overthink your approach in any sales or negotiation scenario.

His methods eliminate the guesswork, giving you a clear roadmap for navigating high-pressure situations.

Why?

Because Voss wasn’t just closing business deals…

He was negotiating with terrorists and kidnappers, where the stakes were literally life and death.

In those critical moments, there’s no time to second-guess what to say or how to handle the conversation.

After retiring from the FBI, Voss launched his own negotiation company and published his best-selling book:

Never Split the Difference: Negotiating As If Your Life Depended On It.

Inside, he shares the same principles he used to save lives.

Principles you can apply to win high-stakes deals, close impossible sales, and turn even the toughest “no” into a resounding “yes.”

If there’s one book on this list that will transform you into a master negotiator, a better communicator, and even a more empathetic human being, it’s this one.

So, grab a copy, start reading, and prepare to revolutionize how you think about negotiation forever.

And thank me later,

Yours Truly,

Patrick Spielmann

P.S. These 5 books aren’t just for sales, they’re life manuals.

Master them, and you won’t just close deals; you’ll command rooms, win hearts, and face any challenge with full confidence that life throws at you.

And remember, like Spider Man’s uncle Ben said…

“With great power comes great responsibility.”
