Most authors make the same mistake.

They finish a manuscript, hand it to friends and family, and ask:

“What do you think?”

The responses are usually warm, supportive, and encouraging.

“It’s great.”

“I loved it.”

“You should publish it.”

That encouragement feels helpful. It can even feel like proof that the book is ready.

But here is the problem: friends and family are usually the worst possible people to judge whether a book has real commercial potential.

They Care About You More Than The Book

This is human nature.

Friends want to support you. Family wants to encourage you. And when someone cares about you, they are often reluctant to say anything that might hurt your feelings.

So instead of assessing the work with complete objectivity, they focus on being kind. They protect your confidence, not necessarily your commercial prospects.

That does not make their feedback dishonest.

It makes it unreliable.

The real question is not whether your mother enjoyed your book.

The real question is whether a stranger would pay for it and recommend it to someone else.

Those are completely different tests.

They Are Not Your Market

Imagine asking someone who never watches football to review a football magazine.

Or asking a vegetarian to judge a steakhouse menu.

Their opinion may be sincere, but it tells you very little about how your intended audience will respond.

Many authors collect feedback from people who would never buy the kind of book they have written.

A retired relative may read your thriller as a favour. A friend may skim your business book because they want to be supportive.

Neither person necessarily represents the reader you need to reach.

The feedback that matters most comes from people who already buy, read, and enjoy books like yours.

They Already Know You

Readers experience a book differently from people who know the author personally.

Your friends know your humour. They understand your stories. They may even fill in gaps because they already know what you mean.

A stranger cannot do that.

If your argument is unclear, your plot is confusing, or your message is weak, a real reader will not give you the benefit of the doubt. They will simply stop reading and move on.

Friends and family often overlook problems that paying customers will not.

Most People Are Not Trained To Give Useful Feedback

Even people who genuinely want to help often do not know how.

They may say they enjoyed a chapter without explaining why. They may feel a section drags but be unable to identify the cause. They may focus on spelling mistakes while missing structural issues entirely.

Useful feedback is a skill.

Most casual readers have never learned how to evaluate pacing, positioning, market fit, reader expectations, or commercial viability.

As a result, their feedback is usually subjective, vague, and difficult to act on.

Encouragement Is Not Market Validation

This is the most dangerous mistake of all.

Encouragement feels like validation. It feels like proof. It feels like evidence that the book is ready.

But encouragement is not demand.

Someone can love your idea and never buy the book. They can praise it and never recommend it. They can support your dream without spending a penny on the finished product.

Commercial success depends on reader demand and buying behaviour, not emotional support.

What Authors Should Do Instead

Friends and family still have value.

They can encourage you. They can celebrate milestones. They can help you stay motivated.

What they cannot do is objectively assess whether your book is likely to succeed in the marketplace.

For that, you need to evaluate:

• Market demand
• Competition
• Reader expectations
• Positioning
• Commercial viability
• Discoverability
• Audience fit

These are the factors that determine whether a book can attract readers and generate sales.

They are also the areas friends and family are least qualified to assess.

The Hard Truth

Most books fail long before publication.

Not because they are badly written. Not because the author lacks talent.

But because nobody honestly evaluated the idea before investing significant time, money, and effort.

The earlier you identify weaknesses, the easier and cheaper they are to fix.

A hard truth before publication costs far less than discovering the same problem after launch.

Friends and family can help you finish a book.

They cannot tell you whether the market wants it.

Those are very different questions.

Before investing in publishing, marketing, editing, or advertising, seek feedback from people who can evaluate the book objectively rather than simply support you emotionally.
