By Dr. Elizabeth Roberts, Psychologist Character Day isn’t just about costumes, it’s a perfect opportunity to weave in a growth mindset lesson. Behind every cape or crown is a character who stumbles, fails, and tries again, and that’s exactly the message kids need to hear.

A Closer Look: Why This Matters
Between beginner and expert lies the awkward, clunky, uncomfortable middle, or the “learning space,” as psychologist Dr. Becky Kennedy calls it. Kids live here every day. Normalizing this messy middle is one of the most powerful tools we can give them for resilience.
In my own practice, I’ve noticed that when children grasp this lesson early, it becomes a catalyst for future growth. Once they expect learning to be messy, they stop fighting embarrassment or shame and lean into the process. Growth takes root faster when kids see mistakes as part of the journey, not proof they can’t do it.
Psych Learning Lens: What Is a Growth Mindset?
Expertise develops slowly, through countless rounds of trial and error. Yet many kids fall into an “all-or-nothing” mindset: I’m good at this or I’m not. I made a mistake, so I must be bad at it.
In reality, they just haven’t practiced enough — yet.
Every expert, from athletes to musicians to scientists, got there by persisting through the clumsy middle. Think of learning a sport or a new language: awkward falls, missteps, and do-overs before smooth skating or fluent conversation.
Research shows that deliberate practice, especially on what you don’t yet know, is the strongest predictor of expertise. Wayne Gretzky famously practiced the shots he missed, while most people rehearse only what they already do well.
Key lessons for kids:
A mistake is just a mistake. It doesn’t define you.
Mistakes are good, they mean you’re stretching your skills.
Learning feels awkward, leaning into that awkwardness makes you grow faster.
Every expert has 1,000+ mistakes behind them. The difference? They kept getting back up.
When kids dress as these characters, they’re stepping into stories of resilience. Teachers can use this to show that failure isn’t the end of the story, it’s how the story moves forward.
Harry Potter fumbles spells again and again before mastering them.
Moana sets sail, fails, and tries again until she finds her way.
Olaf bumbles along, but his optimism and persistence always carry him through.
Athletes and superheroes show grit by getting back up after every loss or fall.
Classroom Activity: When My Character Didn’t Give Up
1. Choose a Character: Each student shares who they’re dressed as. 2. Recall a Struggle: Ask, “When did your character fail, get rejected, or mess up?”
Example: Spider-Man makes mistakes before learning responsibility.
Example: Hermione struggles to fit in before she shines with her intellect.
3. Highlight the Comeback: “What did they do next? How did they keep going?” 4. Personal Connection: Students share or write about a time they didn’t give up and what they learned. 5. Success Ladder: Pick a personal goal and break it into smaller, concrete steps. Show that growth is a staircase, not a leap.
Bringing It Together: Mistakes Fuel Growth
Heroes, and even goofy side characters, remind us that growth comes through mistakes. By drawing these parallels, students see that failure isn’t weakness. It’s the practice ground for courage, persistence, and resilience.
Character Day then becomes more than costumes. It becomes a celebration of the messy, imperfect, and beautiful process of learning. And that, truly, is the real superpower.
