In his life-changing book Think and Grow Rich, Napoleon Hill described six basic fears that impact nearly every person—whether we admit it or not. Most of us live unaware of how these fears influence our decisions, emotions, and even success.
These six core fears are:
- Fear of Poverty
- Fear of Criticism
- Fear of Ill Health
- Fear of Loss of Love
- Fear of Old Age
- Fear of Death
According to Hill, all other fears are minor and can be traced back to one or more of these six. But there’s one fear that is even more dangerous — and most people completely overlook it.
The Most Dangerous Fear: Fear of Negative Influence
This hidden fear doesn’t feel like fear at all. It sneaks in quietly and influences our thoughts, feelings, and beliefs—usually without us realizing. And that’s what makes it so dangerous.
Hill wrote:
“Men who accumulate great riches always protect themselves against this evil. The poverty-stricken never do!”
Negative influence is not something you can touch or see. It’s a state of mind—and your only defense is the intentional use of your willpower.
Here’s how you can protect yourself:
- Understand your own weaknesses, fears, and patterns.
- Acknowledge your human vulnerabilities (everyone has them).
- Surround yourself with people who uplift, challenge, and inspire.
- Avoid passive thinking and stop letting others control your thoughts.
- Use your willpower to actively choose a positive mental environment.

And freedom begins with taking back control of your mind.
“If you are not taking control of your own mind, you can be sure someone else is.”
