"What you say to yourself all day long will determine what you do, what you have, and what you become." — Raymond Hull
"The mind of man is a piece of machinery that must be operated by commands from its owner."
Hull emphasizes that our conscious thoughts are the commands we give to our subconscious mind, which then directs our actions and emotions.
While the term "affirmations" might bring to mind simplistic positive thinking, Hull's approach was grounded in the science of how our brains form and strengthen neural connections. Modern neuroscience confirms his insights, even though he developed them decades earlier.
Every thought you have creates a specific neural firing pattern in your brain. When you repeat a thought, you strengthen the associated neural pathway through a process called long-term potentiation. This is the fundamental mechanism behind learning, habit formation, and ultimately, personality development.
Your brain physically changes in response to repeated thoughts, creating stronger neural connections for frequently used pathways.
What you focus on expands, as your brain's reticular activating system filters information based on your dominant thoughts.
A common misconception is that affirmations are merely about "positive thinking." In reality, Hull's approach is far more sophisticated. He understood that effective affirmations must be:
Hull's genius lies in his development of a systematic method for programming your mind that leverages multiple sensory channels and repetition schedules. This approach, which he called the Triple Impression Technique, involves three key components:
Reading your affirmations engages your visual system and conscious mind. Hull recommends reading each affirmation out loud at least three times daily, with particular emphasis in the morning and evening.
"Read your statements through, at least three times a day. The statement that you will not have to look at once you've read it a few times is not written clearly enough."
Throughout the day, direct your thoughts repeatedly to your affirmations. Visualization is a key component here—creating vivid mental images of already having achieved your goal.
"Think about what you want as often as you can during the day... You must cultivate the habit of directing your thoughts."
The act of writing engages your motor system and deepens the impression. Hull suggests copying your affirmations daily, which literally embeds the neural patterns through physical movement.
"Copy in your own handwriting your statements, every day... Writing your statements will make the deepest impression on your mind."
This three-part approach creates a compounding effect, with each method reinforcing the others. Modern neuroscience confirms that multi-sensory learning creates stronger, more resilient neural pathways.
Once you've created clear goal specifications (as covered in the Goal Clarity section), the next step is to transform them into effective affirmations. This isn't simply restating the goal—it requires reformatting it in a way that maximizes its impact on your subconscious mind.
Affirmation Construction Principles
Write as if the goal is already achieved, not something you want in the future.
Always use "I" statements to personalize the affirmation to your subconscious mind.
Focus on what you want, not what you want to avoid or what you don't want.
Include sensory language that helps your mind create a vivid mental picture.
Hull emphasized that consistency is more important than intensity. A moderate daily practice maintained over time produces far greater results than occasional bursts of high intensity effort. This aligns with modern understanding of habit formation and neuroplasticity.
Modern neuroscience suggests that it takes approximately 30 days of consistent practice to create significant changes in neural pathways. Hull's 30-day recommendation aligns perfectly with this finding, though he arrived at this timeframe through observation rather than brain imaging.
Days 1-10:Initial resistance
Days 11-20:Subtle shifts begin
Days 21-30:New patterns emerge
Hull stressed that the initial period might not show visible external results, but significant internal neural restructuring is occurring. This is why persistence through the early phase is crucial, even when no immediate evidence of change is apparent.
"The greatest difficulty in the practice is to continue while there is not yet any apparent effect."
Take one of your goals from the Goal Clarity exercise and transform it into an effective affirmation using the principles above. Then practice the Triple Impression Technique for at least 7 days.
For best results, include your affirmations in your daily practice routine at the same times each day to build a consistent neural training schedule.
Affirmations can work, with caveats. Decades of self-affirmation research (Cohen & Sherman, 2014, Annual Review of Psychology) show that affirming core values improves problem-solving under stress and openness to change, and neuroimaging (Falk et al., 2015, PNAS) links self-affirmation to activity in the brain’s reward and self-processing regions. They work best when believable and paired with action — exactly how Hull used them.
Write it in the present tense, in positive language, specific and personal — for example, “I am calm and confident speaking to groups” rather than “I will try not to be nervous.” Hull’s rule is to state the goal as already achieved, keep it short enough to memorize, and make it emotionally meaningful to you.
Hull recommends reading each affirmation three times a day. Spacing repetition across the day rather than cramming it leverages the spacing effect, one of the most robust findings in memory research (Cepeda et al., 2006, Psychological Bulletin), which strengthens long-term encoding.
Yes. Research by Wood, Perunovic & Lee (2009, Psychological Science) found grandiose positive statements can backfire for people with low self-esteem because the claim feels untrue. The fix is to keep affirmations believable and values-based, and tie them to concrete action — the action-oriented approach Hull’s system is built on.
