This Monday, during an online meeting with my Korean student, we talked about New Year’s resolutions and parenting. She mentioned how challenging it is to get her daughter to do what she should do. At the time, I happened to be reading Crucial Influence: Leadership Skills to Create Lasting Behavior Change by Joseph Grenny and four co-authors (2013). What struck me was how many of the book’s ideas apply directly to parenting.
The authors argue that key behaviors—whether in adults or children—are shaped by two forces:
(1) Motivation: Does the person want to do it?
(2) Ability: Can the person actually do it?
When someone fails to carry out a task, the reasons almost always come down to one of these two factors: low motivation or insufficient ability.
To address low motivation, effective influencers use three strategies: helping people enjoy tasks they dislike, leveraging role models, and using external rewards or consequences.
1. Stimulating Personal Motivation
This is often the hardest part for parents—especially when dealing with children who love to play but avoid studying. How do we help them enjoy tasks they instinctively resist?
Successful influencers don’t rely on nagging, lectures, or threats. Instead, they use emotional connection and thoughtful questioning to help a person reflect and make their own choice. They tell stories that resonate. They turn dull tasks into small games or challenges. In short, they invite engagement rather than force compliance.
2. Role Models
We’re social creatures; influence is built into our nature. A single compliment, an encouraging gesture, or a small show of approval can shift a child’s behavior. Children naturally look up to those ahead of them.
And of course, we ourselves are often the most powerful role models. If we want our children to change their behavior, we have to demonstrate it in our own. Children learn far more from what we do than from what we say.
3. Rewards and Consequences
Rewards and consequences can work—when used wisely. The key is simple:
Reward the behavior, not just the outcome.
If you want your child to develop the habit of studying independently, reward them when they sit down to study on their own—not only when they bring home a high score.
But internal motivation should always come first. External rewards should follow, not lead. Psychologists call this the overjustification effect: give too many rewards for something a child already enjoys, and you may unintentionally drain the joy out of it. The moment the chocolate stops, so does the piano practice.
Of course, when internal motivation is already strong, rewards enhance rather than harm. A student who loves learning will not love it any less after receiving a scholarship.
These three strategies—creating genuine motivation, leaning on role models, and using rewards wisely—can help children do what they once resisted. And, more importantly, they can help them grow into people who take initiative for themselves.
The book puts it well: “Learning how to motivate and enable others to change their actions may be the most important skill you'll ever acquire.” (p. 9)
Perhaps, at the heart of parenting is influence—not controlling our children, but helping them learn to control themselves by building the motivation and ability to navigate life on their own. That is why these ideas matter. They remind us that change is about understanding how people grow. If we can learn to influence with empathy, clarity, and patience, we are not just shaping behaviors; we are shaping character—and ultimately, fate.
