During a Crunchyroll interview to celebrate 20 years of "Naruto," Briana Lawrence interviewed Maile Flanagan to dissect her part in the franchise and what portraying the character means to her. Lawrence asked Flanagan if Naruto had taught her anything that she takes to heart in her everyday life.
Flanagan responded by mentioning Naruto's iconic "never give up" attitude and catchphrase. She continued by saying that Naruto's signature catchphrase "is certainly inspirational. I think it means a lot to people. I do appearances and conventions, and the guy who was helping me out this last week said, 'Okay, I counted four grown men that cried.' ... I think it's taught me to never give up. I say it so much that maybe it's subliminal."
The visual of multiple grown men bursting into tears at a convention is a testament to how much the franchise means and what it stands for. Many adult fans were children or teenagers when they first invested in the show. As Flanagan said, never giving up is an inspirational and powerful message. She appears to have adopted it in her everyday life because she's said it so much, but fans have heard it just as much, so it resonates with them. For many of them, Naruto's persistence may have been a huge part of their formative years.
