“Your ability to use the principle of autosuggestion will depend, very largely, upon your capacity to concentrate upon a given desire until that desire becomes a burning obsession.” — Napoleon Hill
Auto-suggestion is the third principle in Hill’s system, and it serves as the operational bridge between the two that came before it. Desire (Chapter 1) tells you what you want. Faith (Chapter 2) tells you that you can have it. Auto-suggestion is the how — the specific mechanism by which you communicate both of those things to the part of the mind that actually makes things happen.
The subconscious mind, Hill explains, can be reached through the five senses. But the most powerful and reliable route is through the sense of hearing — specifically, through the words you repeat to yourself, aloud or internally, with emotional conviction. Every thought you allow to dominate your mind eventually sinks into the subconscious and influences your behavior, whether you intend it to or not. Auto-suggestion is simply the practice of controlling which thoughts get that dominant position.
Most people practice auto-suggestion unconsciously and badly. They repeat negative self-talk — “I can’t afford that,” “I always mess things up,” “People like me never get ahead” — with strong emotion and frequent repetition, and then wonder why their lives seem to confirm those beliefs. Hill’s argument is that the same principle, applied deliberately and positively, produces the opposite result.
The subconscious mind does not reason, debate, or evaluate. It accepts what it is repeatedly and emotionally given. Think of it as fertile soil: it will grow whatever seeds you plant, regardless of whether those seeds are weeds or flowers. This is why Hill is so insistent on the combination of repetition and emotion. Repetition alone plants the seed. Emotion is the water that makes it grow.
When you read your desire statement with genuine feeling — picturing yourself already in possession of the goal, feeling the pride, relief, and excitement that accompany it — you are doing more than affirming a positive thought. You are sending a chemically encoded signal to your subconscious that says: “This is real. Act on it.”
Hill provides a clear three-step procedure for applying the auto-suggestion principle:
Write a clear statement that includes:
The specificity is not arbitrary. Vague desires produce vague subconscious instructions. The more precisely you can define what you want, the more precisely the subconscious can work toward it.
Read your statement aloud once before sleeping and once upon waking. The timing is deliberate:
Reading aloud rather than silently is important. The act of speaking activates the auditory channel and reinforces the instruction through an additional sense.
This is the step most people neglect. As you read your statement, you must simultaneously:
Hill acknowledges that this feels forced at first. The mind rebels against believing something it hasn’t experienced yet. His response: do it anyway. The subconscious is not moved by what is true today. It is moved by what is repeatedly presented as true. With consistent practice, the feeling of “forced” gradually gives way to genuine conviction.
Hill is unusually candid about the most common failure mode: people read affirmations without feeling. They go through the motions without engaging the emotional component, get bored or skeptical after a few days, and conclude that “this doesn’t work.”
What they’ve actually demonstrated is that words without emotion don’t reach the subconscious. This is not a failure of the principle. It is a failure to apply it correctly.
Auto-suggestion and imagination are inseparable. When Hill asks you to visualize yourself already in possession of your desire, he is asking you to use your imagination as a tool of instruction. The more vivid, specific, and emotionally rich the mental image, the more powerfully it is received by the subconscious.
This is why Hill places the chapter on imagination (Chapter 5) shortly after this one. The imagination is the workshop in which the raw material of desire is shaped into a specific mental blueprint — and that blueprint is then delivered to the subconscious through auto-suggestion.
If auto-suggestion is a broadcasting system for planting thoughts in the subconscious, then the mind must also be protected from unwanted broadcasts. Hill is explicit: negative thoughts, allowed to dominate the mind with emotional intensity, will plant seeds of failure just as surely as positive ones plant seeds of success.
This means being intentional about:
Before each session of reading your desire statement, spend sixty seconds deliberately summoning one of the following emotions:
These are what Hill calls the “positive emotions.” Their presence during auto-suggestion amplifies the signal sent to the subconscious. Their absence makes the practice mechanical and ineffective.
Do not begin reading until you can genuinely feel one of these emotions, even if only a small degree. The feeling is the fuel.
What are the most frequent thoughts you repeat to yourself throughout the day? Are they instructions you would consciously choose to give your subconscious, or are they programming from habit, fear, or other people’s expectations? If your inner monologue were a radio station, what would it be broadcasting — and is that the signal you want your subconscious to receive?
